  The present invention relates to a ball removal mechanism for a gaming machine including a ball tray that stores a game ball in a ball tray structure that projects from a front surface of the gaming machine.

  A pachinko machine is widely known as a gaming machine that has a ball tray structure projecting from the front surface of a gaming machine and is equipped with a ball removal mechanism. In a pachinko machine, a lower ball tray structure is attached to the front lower part of the front frame that accommodates and holds the game board, and a lower ball tray structure is attached to the lower ball tray structure to store the game balls. And an ashtray. A ball outlet that communicates with the upper and lower sides is formed at the bottom of the lower ball tray, and a valve element that can be opened and closed on the back side of the ball outlet and an opening / closing operation of the valve element. For example, when the lower ball tray is becoming full, or when the pachinko game is finished, the player manually operates the operation part of the operation member. The opening is opened, and the game ball can be dropped and stored in a ball box prepared below the ball opening.

Such a ball removal mechanism is provided with a valve body that is slidable in the left-right direction or the front-rear direction on the back side of the ball removal opening, and an operation unit that can be operated to displace the valve body in the front center of the lower ball tray structure The valve is moved in the opening direction when the operation part is slid in the left direction or is pressed backward (pachinko machine side) to open the ball outlet (for example, (See Patent Document 1).
JP 7-313707 A

  However, the operation part in the conventional ball removing mechanism is generally provided at the center of the front side (front side) that protrudes most forward in the lower ball tray structure so as to face the player. When a person stands up or sits down from a seat, or turns to take a ball box left in an adjacent pachinko machine, he or she strikes the lower ball tray structure and slides or presses the operation unit. As a result, there is a problem that game balls may be scattered around.

  In addition, it is relatively easy to complete the game and perform the ball removal operation with both hands free. For example, while the big hit is occurring, the ball release operation is performed with the left hand while the firing handle is rotated. However, it was unpleasant and difficult to operate.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a ball removal mechanism that can effectively prevent the scattering of game balls due to an erroneous operation and has good operability.

In order to achieve the above object, in the ball removal mechanism of the present invention, the front view of the gaming machine viewed from the front has a ball bowl structure provided in a protruding manner on the front surface of the gaming machine and has a ball removal opening at the bottom. A ball tray that stores game balls in a tray portion that opens to the left, an ashtray that is provided on the left side of the ball tray and opens upward, and a ball tray and an ashtray that have a certain width in the left-right direction between the ball tray and the ashtray A partition wall that protrudes upward from the upper surface of the opening, a main body that is slidably supported back and forth inside the partition wall, and a ball outlet that extends from the main body to the right along the bottom surface of the pan A shutter part that opens and closes, and a valve body that has an operation part that protrudes rightward from the main body part through a lever insertion part formed on the right side surface of the partition wall and is slidable back and forth, The ball tray structure consists of a base body molded with a ball tray and the bottom surface of the base body. And a ball outlet is formed at the bottom left side of the ball tray in the base body, and a discharge port that opens up and down communicates with the ball outlet through the shutter on the bottom side of the outer body. A rail that supports the main body of the valve body so as to be slidable in the front-rear direction is provided on the left side of the discharge port, and the valve body is slid by a sliding operation on the operation unit to open the ball outlet. The game balls that flow down through the ball outlets are prevented from being transferred into the partition walls by the rails.
Preferably, the ball outlet is formed to open from the bottom surface to the left side surface that extends from the bottom surface to the upper left side of the ball tray, and the rail is formed to a height position near the upper edge of the ball outlet. Further, between the base body and the exterior body, a forward transfer prevention wall and a right side transfer prevention wall are provided below the ball extraction opening and extending forward and rightward of the ball extraction opening. the front end is provided with a rear transference prevention wall extending downwardly, when the valve body is opened ball vent opening is slid, the base body and the outer body of the game ball flowing down through the ball vent port It is preferable that the moving-in is prevented from being caused by the rail, the front moving-in prevention wall, the right-side moving-in preventing wall and the rear moving-in preventing wall .

In such a ball removal mechanism, an operation portion for performing an opening / closing operation of the ball removal opening is provided on a partition wall that is located on the left side of the ball tray in the ball tray structure and protrudes upward . For this reason, when a player tries to stand up or sit down from a seat or turns to the side to take a ball box left in an adjacent pachinko machine, he hits the front of the lower ball tray structure. However, there is a low possibility that the operation unit is erroneously operated in the opening direction, and a situation in which the game balls are scattered around can be suppressed. In addition, since the operation unit is provided on the left side of the ball tray, the ball removal operation can be easily performed with the left hand while the firing handle is rotated with the right hand.
Moreover, since the partition wall which protrudes upwards from the opening upper surface of a ball tray and an ashtray is formed between a ball tray and an ashtray, it suppresses the traffic of a game ball and ash between a ball tray and an ashtray For example, even if a player tries to lift the game ball stored in the lower ball tray to the upper ball tray and the game ball overflows from the lower ball tray, the overflowed game ball is blocked by the partition wall and is dropped into the ashtray. The cigarette ash on the ashtray side does not overflow and enter the lower ball tray so that the game ball is not covered with ash. In addition, the valve body is housed inside the partition wall so as to be slidable back and forth, and a lever insertion part is formed on the right side wall of the partition wall. A mechanism can be provided, and tobacco ash, dust, and the like are less likely to enter the partition wall. Furthermore, when the valve body is slid along the rail to open the ball outlet, the rail prevents the game ball flowing down through the ball outlet from entering the partition wall. That is, the rail has a function of not only a function of supporting the valve body so as to be slidable back and forth but also a function of a transfer-in preventing wall for preventing the game ball from moving into the partition wall.

  Therefore, according to the present invention, it is possible to provide a ball removal mechanism that can suppress the scattering of game balls due to an erroneous operation and that has good operability for the player.

  In the ashtray structure AT2 in which each part is configured in this manner, by engaging the latching groove 75 of the ashtray 70 with the latching protrusion 85 of the housing recess 80 and fitting the locking pin 77 to the pin receiving part 87, The ashtray 70 is detachably attached to the housing recess 80.

  When the ashtray 70 is mounted, the ashtray 70 is fitted in a forward tilted posture from the upper front side of the housing recess 80 as shown in FIG. 6, and the left and right edge portions 53 of the ashtray 70 are attached to the left and right support rail portions 63 of the housing recess 80. The latch groove 75 is engaged with the latch protrusion 85 by being supported and guided. Then, the front end side of the ashtray 70 is swung downward with the engaging portion of the locking groove 75 and the latching protrusion 85 as a fulcrum, and the guide protrusion 73 is slid so as to slide along the guide groove 83.

  Then, the taper surface formed at the tip of the locking pin 77 enters and engages with the pin receiving portion 87 from obliquely above, and the left and right clamp arms 86 are elastically deformed so as to push open the pin receiving portion 87. The locking pin 77 is fitted into the receiving portion 87 and locked in a state of being elastically held between the left and right clamp arms 86. At this time, the ashtray bottom surface 57 is engaged with the support surface of the support pedestal 67, the left and right edge portions 53 and the surrounding wall portion 54 are engaged with the support rail portion 63, and the guide protrusion 73 is engaged with the bottom portion of the guide groove 83. The ashtray 70 is mounted in the housing recess 80.

  In the state in which the ashtray 70 is mounted, a partition wall 64 that extends higher than the upper surface of both openings exists between the lower ball tray 23 and the ashtray 70, and between the lower ball tray 23 and the ashtray 70. The game balls and ashes are difficult to come and go. For this reason, for example, even if the player tries to scoop up the game balls stored in the lower ball tray 23 and overflows from the lower ball tray 23, the overflowed game balls are blocked by the partition wall 64 and moved to the ashtray 70 side. The cigarette temporarily placed on the ashtray 70 rolls and falls to the lower ball tray 23, or the ash of the cigarettes accommodated in the container portions 51 and 52 overflows and disappears into the lower ball tray 23. There is no such thing as a mixed game ball covered with ash. Further, since the partition wall 64 has a certain width and is tilted downward, even if the game ball rides on the upper surface of the partition wall 64, the partition wall 64 is guided forward and the ashtray 70 side. It has a structure that is difficult to fall down.

  In the ashtray structure AT2, the bottom cover 68 and the support pedestal 67 are formed short so that the lower surface side of the frosted portion 51 is open. For this reason, the heat dissipation property of the frosted portion 51, which has the highest frequency among the portions of the ashtray 70, is good, and the ashtray is prevented from overheating due to the fire of the temporarily placed cigarette and the fired type of the smoked tobacco. 70 damage can be suppressed. The support pedestal 67 that supports the lower surface of the cigarette butt storage portion 52 is provided with spacer ribs 67r to form a saw-like shape, and a heat radiation space is formed between the bottom cover 68 and the support pedestal 67. For this reason, thermal deformation and deterioration of the base body 21 can be suppressed without the heat transmitted from the ashtray bottom surface 57 being stored.

  On the other hand, when removing the mounted ashtray 70, a finger is placed on the lower end surface of the locking pin 77 or the lower surface of the eraser 51 and pulled up, and the engaging portion of the latching groove 75 and the latching projection 85 is used as a fulcrum. Then, the front end side of the ashtray 70 is swung upward. Then, the locking pin 77 elastically clamped by the pin receiving portion 87 is released and the locking is released, and the guide projection 73 moves upward so as to slide on the inclined surface of the guide groove 83, and the engagement of each portion is released. Is done. Therefore, the ashtray 70 is removed from the housing recess 80 by pulling out the ashtray 70 from the horizontal front side to the upper side.

  For this reason, the attendant of the game facility can easily attach and detach the ashtray 70. The ashtray 70 is provided on the left side of the front surface of the ball tray structure 20, and a clerk of the game facility can remove and remove the ashtray 70 without interfering with the player's game, and collect the butts in a bucket or the like behind the player. Therefore, unlike a conventional rotating ashtray, the collection operation does not accidentally sprinkle butts and ash around. In addition, when the ashtray 70 is very dirty during daily inspections or panel replacement, the ashtray 70 can be removed and washed and washed. If the ashtray 70 is damaged, the ashtray 70 can be easily replaced. can do. Accordingly, the above-described ashtray structure AT2 can also solve various problems that have been regarded as conventional problems, and by providing such an ashtray structure, it is easy to handle and comfortable for both players and amusement facilities. A gaming environment can be provided.

  In the ashtray structure AT2, the latching groove 75 and the latching pin 77 are provided on the ashtray 70 side, and the latching projection 85 and the latching pin that engage with the latching groove are received and latched. Although the example provided in the accommodation recessed part 80 side was shown, as for the arrangement position of these parts, the ashtray 70 side and the accommodation recessed part 80 side may be comprised reversely, and it latches without forming the latching groove 75 The protrusion 85 may be configured to engage with the upper end portion of the surrounding wall 54.

  Now, adjacent to the above-described ashtray structure AT (AT1 or AT2), the game balls stored in the lower ball tray 23 are dropped into the ball box BB prepared below the lower ball tray structure 20 to be stored. A punching mechanism BM is provided. The inventor has devised various ball configuration mechanisms BM in order to solve the problems described in the headline and achieve the object. Hereinafter, the ball configuration mechanisms BM1 to BM6 of each configuration mode will be described in order.

FIG. 13 is a side sectional view of the ball removal mechanism BM1a as viewed from the lower ball dish 23 side, and FIG. 13 is a side sectional view of the ball removal mechanism BM1a with the ball removal opening opened.

  As described above with reference to FIG. 7, the lower ball dish structure 20 includes the base body 21 that forms the base of the lower ball dish structure 20, and the exterior body 22 that forms the outer shell of the lower ball dish structure 20. , The outer body 22 is engaged from the front of the base body 21 and the outer body 22 is screwed from the rear surface side of the base body 21 to form an integrated assembly.

  The base body 21 is integrally formed with a lower ball tray 23 that is loose and has a bottom surface that is inclined forward and to the left (ashtray structure side) to form a deep dish with an open top surface. A ball outlet 24 that communicates vertically with the left side wall is formed.

  A partition wall engaging portion 101 that is aligned with the inner shape of the partition wall 64 formed on the exterior body 22 and that can be engaged and disengaged in the front-rear direction is provided at the upper left of the lower ball tray 23. 101 is cut out to form a slide range restricting portion 102 that defines the movable range of the operation member 130 between a closed position and an open position, and a slit-like lever insertion hole 103 communicating vertically is formed below the slide range restricting portion 102. Has been. On the lower surface side of the lower ball tray 23, a front transfer prevention wall 105 that is located in front of the ball outlet 24 and protrudes downward, and a right side entry prevention that is located on the right side of the ball outlet 24 and protrudes downward. A wall 106 is provided so that game balls flowing down from the ball outlet 24 do not enter between the bottom surface of the lower ball tray 23 and the outer body 22.

  The exterior body 22 is formed in an outer shell cover shape that covers the upper and lower surfaces and the front surface of the base body 21 excluding the housing recess 60 (80) of the ashtray structure AT and the upper opening surface of the lower ball tray 23 as a whole. On the bottom surface side of the outer package 22, there is formed an opening 25 having a larger opening width than the ball outlet 24 on the lower ball tray side and located below the ball outlet 24 in the assembled state and communicating vertically. ing. A rib flange that engages with the upper edge flange surface of the lower ball tray 23 is formed on the side wall of the partition wall 64 on the lower ball tray side. A lever insertion portion 113 that allows the operation member 130 to be inserted to the left and right is formed.

  Below the partition wall 64, an L-shaped left-hand side transfer prevention wall 116 that protrudes inwardly from the front wall surface and bottom surface of the exterior body 22 is formed, and above the lower region of the partition wall 64 and the lower ball tray 23 side. Are formed in the left and right. The formation position of the left side transfer prevention wall 116 is formed in accordance with the left edge of the opening of the discharge port 25, and the rigidity of the exterior body 22 is improved by connecting the front wall surface and the bottom surface in an L shape, and the ball outlet port is formed. The game ball falling from 24 is guided to the discharge port 25 so that the game ball does not enter between the base body 21 and the exterior body 22. Formed on the left side of the left side transfer prevention wall 116 is a T-shaped slide rail 112 that protrudes from the bottom surface and extends in front and rear in parallel with the left side transfer prevention wall 116.

  For this reason, when the exterior body 22 is covered and engaged from the front of the base body 21, the right wall surface of the housing recess 60, the left wall surface of the lower ball tray 23, the partition wall engaging portion 101, below the partition wall 64, A trapezoidal storage space (referred to as a valve body storage portion) 111 extending in the front-rear direction and surrounded by the slide rail 112 is formed. A columnar spring support column 107 having an outer diameter somewhat smaller than the inner diameter of the coil spring 147 is formed on the standing wall surface of the base body 21 in the inner part of the valve body accommodating portion 111 so as to protrude forward. A guide label 118 is attached to the upper surface of the partition wall 64 to explain the operation of the ball removal mechanism.

  On the other hand, the valve body 120 is mainly composed of a hollow block-shaped main body part 121 extending in the front-rear direction, and a shutter part 124 formed at the lower part of the main body part 121 so as to extend to the right side (the side of the bowl). It is integrally molded by molding means such as injection molding using a thermoplastic resin material such as ABS resin.

  The main body 121 is formed in a trapezoidal shape in which the projected shape in front view is matched with the cross-sectional shape of the valve body accommodating portion 111 in the lower ball tray structure 20, and the slide rail 112 is formed on the lower surface of the main body 121. A combined concave rail engaging portion 122 is formed, and when the valve body 120 is accommodated in the valve body accommodating portion 111, the rail engaging portion 122 is engaged with and supported by the slide rail 112, and the main body portion 121 is engaged with the upper and left and right wall surfaces of the valve body accommodating portion 111 so as to be slidably supported in the front-rear direction. A lever fitting hole 123 for receiving and fixing the fitting protrusion 133 of the operation member is formed on the upper surface of the main body 121, and the inner center of the main body 121 is somewhat larger than the outer diameter of the coil spring 147. A cylindrical spring accommodating portion 127 having a large inner diameter is formed to open rearward.

  The shutter part 124 is formed in a plate shape that protrudes to the right from the lower part of the main body part 121 in accordance with the height position on the lower surface side of the ball outlet 24, and the protruding width in the left-right direction and the dimension in the front-rear direction are the same. It is formed slightly larger than the opening width and opening size of the mouth 24. On the other hand, the ball outlet 24 is formed in front of the lower ball tray 23, and the dimension from the opening rear edge of the ball outlet 24 to the standing wall surface of the base body 21 is set to be larger than the longitudinal dimension of the shutter portion 124. ing.

  For this reason, when the valve body 120 is slid back and forth, the shutter portion 124 closes the entire opening of the ball outlet 24 in a closed position, which will be described later, and the shutter portion 124 stands on the standing wall surface of the base body 21 in the open position. The entire opening of the ball outlet 24 can be completely opened without coming into contact with. In this configuration example, since the ball outlet 24 is enlarged and formed to the left side wall of the lower ball tray 23, the front-rear dimension of the main body 121 is also formed to match the front-rear dimension of the shutter part 124. .

  At the front end of the shutter portion 124, a rearward transfer prevention wall 125 is formed extending downward, and the game balls flowing down from the ball outlet 24 when the shutter portion 124 is opened are placed on the bottom surface of the lower ball tray 23 and the exterior body. 22 is not allowed to enter. Further, a strip-like left-side slide-in prevention wall 126 is formed on the lower part of the main body 121 so as to protrude forward. When the shutter part 124 is opened, the left-side inward prevention wall 116 is formed from the front of the ball outlet 24. It is configured so that the game ball does not move into the valve body housing part 111 beyond.

  The operation member 130 fixed to the valve body 120 includes a lever part 131 molded in an L-shaped angle shape and an operation part 135 press-fitted and fixed to the distal end side of the lever part 131. On the base end side of the lever portion, a fitting protrusion 133 to be fitted in a lever fitting hole 123 formed on the upper surface of the main body portion of the valve body 120 is provided, and on the distal end side of the lever portion 131 is a press-fit shaft at the lower end of the operation portion 135. A boss portion is formed to receive the. The upper end of the operation unit 135 is formed in a spherical shape so that the finger-hanging operation is easy. Both the lever part 131 and the operation part 135 can be formed using a resin material or a metal material, or both can be integrally molded. In this configuration example, a resin material is used for the lever part 131. Used, a metal material is used for the operation unit 135 to achieve both mass production cost and durability.

  Each member configured in this manner is assembled between the base body 21 and the exterior body 22 in the assembly process of the lower ball tray structure 20 to form a ball removal mechanism BM1a.

  For assembly, first, one end of the coil spring 147 is supported by the spring support 107 of the base body 21, and the right side surface of the valve body 120 and the shutter portion 124 are supported along the left side surface and the lower surface of the lower ball dish 23 from the front. The other end side of the coil spring 147 is accommodated in the spring accommodating portion 127 on the back surface of the valve body (see FIG. 8). Thus, the coil spring 147 is supported between the spring support 107 on the base body side and the spring accommodating portion 127 on the valve body so as to be elastically movable back and forth. Therefore, the valve body 120 is pressed rearward so that the lever fitting hole 123 on the upper surface of the valve body is positioned below the lever insertion hole 103 of the base body, and the fitting protrusion 133 of the operation member 130 is inserted from above the lever insertion hole 103. It is inserted and fixed to the lever fitting hole 123 by press-fitting. At this time, the fitting protrusion 133 may be fixed to the lever fitting hole 123 using an adhesive as necessary.

  Thus, the urging force of the coil spring 147 is supported by the base body 21 by the engagement relationship between the operation member 130 and the slide range restricting portion 102 and is sandwiched between the spring column 107 and the spring accommodating portion 147. Thus, the front side surface of the operation member 130 (lever portion 131) is urged and supported at a position where it abuts against the front end wall surface of the slide range restricting portion 102.

  Next, the exterior body 22 is mounted so as to cover the base body 21 from the front. At this time, the partition wall engaging portion 101 of the base body engages with the partition wall 64 to position the exterior body 22 in the left-right direction and functions as a slide guide for guiding the exterior body 22. When the exterior body 22 is slid until the rear end portion of the partition wall 64 reaches the front end position of the slide range restricting portion 102, the rib flange of the partition wall 64 contacts the lever portion 131. Therefore, the right wall surface of the partition wall 64 is elastically deformed so as to open obliquely upward, and the lever portion 131 is moved over and introduced into the lever insertion portion 113. At this time, on the left side of the partition wall 64, the left side surface of the main body 121 of the valve body 120 is engaged with the right wall surface of the housing recess 60, and the rail engaging portion 122 of the valve body is engaged with the slide rail 112.

  Then, it slides until each rear-end part of the exterior body 22 contact | abuts to the standing wall surface of the base body 21, and it tightens by screwing a screw from the rear surface side of the base body 21 to the screw boss | hub of the exterior body aligned in abutting state. Thus, the ball removal mechanism BM1a is assembled, and the lower ball dish structure 20 having the ball removal mechanism is formed.

  When the ball removal mechanism BM1a is assembled in this way, the valve body 120 is accommodated and supported in the valve body accommodating portion 111 below the partition wall 64 so as to be horizontally displaceable in the front-rear direction, and is always urged forward by the coil spring 147. A restriction position where the operation member 130 contacts the front end surface of the slide range restriction portion 102, specifically, a closed position where the main body portion 121 and the shutter portion 124 of the valve body 120 close the entire opening on the back side of the ball outlet 24. Held (see FIG. 12). Accordingly, the game balls discharged from the lower ball tray discharge passage through the discharge bucket 18 and the lower outlet 17 to the lower ball tray 23 are restricted in flow by the valve body 120 in the closed position and stored in the lower ball tray 23. Is done.

In order to perform the ball removal operation, the operation portion 135 of the operation member 130 is pressed backward against the urging force of the coil spring 147. Then, the valve body 120 slides backward in the valve body accommodating portion 111, the main body portion 121 and the shutter portion 124 move rearward, and the ball outlet 24 is opened (see FIG. 11). When the operating member 130 is pressed to the restricting position abutting the rear end surface of the sliding range restriction unit 102, in the open position the main body portion 121 and the shutter 124 of the valve body 120 opens the entire opening of the sphere vent port 24 Disposed (see FIG. 13). Accordingly, the game balls stored in the lower ball tray 23 flow down to the ball box BB prepared below through the ball outlet 24 and the discharge port 25.

  Here, on the lower side of the ball outlet 24, the front entrance prevention wall 105 is located in front of the ball exit 24, the right side entrance prevention wall 106 is located on the right side, the left side entrance prevention wall 116 is located on the left side, and the front end of the shutter portion 124. Further, a rearward transfer prevention wall 125 is provided, and a left-side slide transfer prevention wall 126 is provided in front of the main body 121. For this reason, when the valve body 120 is opened, the lower periphery of the ball outlet 24 is surrounded by these transfer-in prevention walls to form a duct-shaped discharge path, and the game flows down from the ball outlet 24 to the discharge port 25. A sphere does not enter between the base body 21 and the exterior body 22.

  Further, in the ball removal mechanism BM1a, the spring strut 107 that supports the inner periphery of the coil spring 147 and the spring accommodating portion 127 that supports the outer periphery of the coil spring 147 support the front and rear of the coil spring 147, and the spring accommodating portion 127 is It is formed inside the main body of the valve body 120. For this reason, in the open position of the valve body 120, the spring column 107 protruding forward from the base body is received in the valve body 120 moved rearward (inside the spring accommodating portion 127), and the coil spring 147 is also substantially entirely. It is accommodated inside the valve body 120 (same as above). Therefore, it is possible to configure a ball removal mechanism having a large opening size with a compact configuration.

  When the ball removal operation is finished, the pressing force for holding the operation unit 135 in the open position may be weakened. When the forward pressing force is weakened, the coil spring 147 self-resets in the extending direction by the elastic force accumulated in the coil spring 147, and the valve body 120 slides forward in the valve body housing portion 111, The part 121 and the shutter part 124 close the ball outlet 24. When the operating member 130 comes into contact with the front end surface of the slide range restricting portion 102, the forward movement of the valve body 120 is restricted, and the main body 121 and the shutter portion 124 are held in the ball outlet 24 while maintaining a predetermined urging force. Is held in a closed position that closes the entire opening on the back side (see FIG. 12).

  As described above, in the ball removal mechanism BM1a of this configuration, the operation unit 135 for opening and closing the ball removal opening 24 is located on the left side of the lower ball dish 23 and slides in the front-rear direction on the upper surface side of the lower ball dish structure 20. Since it is provided so as to be operable, it is possible to easily perform the ball removing operation with the left hand while rotating the firing handle 14 with the right hand, and the distance between the lower ball tray structure 20 and the abdomen is in close contact. Even such a player can easily perform the ball removal operation.

  In addition, since the operation unit 135 is provided on the upper surface side of the lower ball tray structure 20 so as to be slidable in the front-rear direction, when the player tries to stand up or sit down from the seat or is left in the adjacent pachinko machine. When the player tries to take a ball box and turns to the side, the operation unit 135 may be erroneously operated in the opening direction even if it hits the front surface of the lower ball tray structure 20, and the ball outlet 24 may be opened. There is no such situation that the game balls are scattered around. Further, the main component of the ball removing mechanism is configured by effectively using the lower region of the partition wall 64, and the operation unit 135 is disposed to protrude from the partition wall 64 toward the lower ball tray 23, so that the compact configuration Thus, it is possible to provide a ball removal mechanism with good operability. Further, since the lever insertion portion 113 through which the operation member 130 is inserted is formed on the side surface of the partition wall 64 on the side of the lower ball tray 23, the structure is such that cigarette ash, dust, and the like do not easily enter the ball removal mechanism. ing.

  Therefore, according to the ball removal mechanism BM1a described above, it is possible to effectively prevent the game balls from being scattered due to an erroneous operation, and to provide a ball removal mechanism with good operability for the player.

(Ball removal mechanism BM1b)
Next, similarly to the above-described ball removal mechanism BM1a, the second configuration example of the ball removal mechanism BM1 of the first configuration form in which the operation member is provided on the upper left side of the lower ball dish structure 20 so as to be slidable in the front-rear direction. The ball removal mechanism BM1b will be described with reference to FIGS. 14 is a perspective view of the structure of the ball removal mechanism BM1b as viewed obliquely from the front, FIG. 15 is a sectional view of the ball removal mechanism BM1b as viewed from the front side, and FIG. 16 is a plan view of the ball removal mechanism BM1b. The basic structure of the lower ball tray structure 20 and the ashtray structure AT1 are the same as the ball removing mechanism BM1a of the first configuration example described above. The description will focus on the differences.

  A partition wall engaging portion 151 that is detachable in the front-rear direction in alignment with the inner shape of the partition wall 64 formed in the exterior body 22 is provided on the upper left side of the lower ball tray 23 in the base body 21. A slit-like lever insertion hole 153 that communicates with the left and right is formed in the lower portion of the right side wall of the wall engaging portion 151. The front and rear ends of the lever insertion hole 153 are closed, thereby forming a slide range restricting portion 152 that defines the movable range of the operation member 180 between the closed position and the open position. The left side wall of the partition wall engaging portion 151 is partially cut away from the left side wall corresponding to the front end position of the slide range restricting portion 152, and the set recess 154 that allows the operation member 180 to be inserted horizontally through the lever insertion hole 153. Is formed.

  On the other hand, on the exterior body 22 side, a rib flange that engages with the upper edge flange surface of the lower ball tray 23 is formed in the lower part of the right side wall of the partition wall 64, and is aligned with the formation position of the lever insertion hole 153 on the base body 21 side. Thus, a lever insertion portion 163 for inserting the operation member 180 to the left and right is formed. Below the partition wall 64, two rib-like slide rails 162, 162 projecting inward from the front wall surface and bottom surface of the exterior body 22 and extending in the front-rear direction are formed side by side in parallel.

  These slide rails 162 are formed in an L-shaped frame connecting the front wall surface and the bottom surface to improve the rigidity of the exterior body 22, and the right slide rail is aligned with the left edge of the opening of the discharge port 25. 24 is formed so as to be close to the upper edge of the opening, and the game ball flowing down from the ball outlet 24 is guided to the discharge port 25 so that the game ball does not enter between the base body 21 and the exterior body 22. Yes. That is, the slide rail 162 of this configuration example not only functions as a slide rail that supports the valve body 170 so as to be slidable back and forth, but also functions as a reinforcing frame of the exterior body 22, the left-side entry prevention wall 116 and the left side described above. It has the structure which has the function of the direction slide transfer prevention wall 126.

  When the exterior body 22 is covered and engaged from the front of the base body 21, the right side wall surface of the housing recess 60, the left side wall surface of the lower ball tray 23, the partition wall engaging portion 151, and the slide rail are provided below the partition wall 64. A valve body accommodating portion 161 having a trapezoidal cross-sectional view extending in the front-rear direction surrounded by 162 is formed.

  The valve body 170 includes a hollow block-shaped main body portion 171 formed in accordance with the cross-sectional shape of the valve body housing portion 161, a shutter portion 174 formed to extend to the right side below the main body portion 171, and a main body portion. The L-shaped operation member 180 that protrudes upward from the upper surface of 171 and extends to the right is mainly used, and is molded using the same resin material as the valve body 120 described above. In the ball removal mechanism BM1b, the operation member 180 is formed integrally with the valve body 170, and an arcuate operation portion 185 is formed at the tip of the operation member 180.

  On the lower surface of the main body portion 171, concave rail engaging portions 172 and 172 detachably engageable with the left and right slide rails 162 and 162 are formed extending forward and backward, and the valve body 170 is accommodated in the valve body accommodating portion 161. Sometimes, the rail engaging portion 172 is engaged with and supported by the slide rail 162, and the main body portion 171 is engaged with the upper and left and right wall surfaces of the valve body accommodating portion 161 so as to be slidably supported in the front-rear direction. It is like that. A cylindrical spring accommodating portion 127 is formed at the inner center of the main body portion 171 so as to open rearward.

  The shutter portion 174 is formed in a plate shape that protrudes rightward from the lower portion of the main body portion 171 in accordance with the height position of the lower surface side of the ball outlet 24, and has a protruding width in the left-right direction and a dimension in the front-rear direction. It is formed slightly larger than the opening width and opening size of the mouth 24. Here, the ball outlet 24 is formed in front of the lower ball tray 23, and the dimension from the opening rear edge of the ball outlet 24 to the standing wall surface of the base body 21 is set to be larger than the front-rear direction dimension of the shutter portion 174. ing.

  For this reason, the shutter 174 closes the entire opening of the ball outlet 24 when the valve body 170 is positioned at the closed position, while the ball outlet 24 can be completely opened at the open position. . A rearward transfer prevention wall 175 that extends downward is formed at the front end of the shutter portion 174, and the game balls that flow down from the ball outlet 24 when the shutter portion 174 is opened are located on the bottom surface of the lower ball tray 23, the exterior body 22, and the like. It is supposed not to get in between.

  Each member configured in this manner is assembled between the base body 21 and the exterior body 22 to form a ball removal mechanism BM1b. For assembly, the end of the coil spring 147 is supported by the spring support 107 of the base body, and the operation unit 180 is aligned with the set recess 154 from the left side of the lower ball tray 23 and is inserted into the lever insertion hole 153. The right side surface of the portion 171 and the shutter portion 174 are supported on the left side surface and the bottom surface of the lower ball tray 23, and the other end side of the coil spring 147 is accommodated in the spring accommodating portion 127 on the back surface of the valve body. Thus, the coil spring 147 is supported between the spring support 107 on the base body side and the spring accommodating portion 127 on the valve body so as to be elastically movable back and forth.

  Next, the exterior body 22 is mounted so as to cover the base body 21 from the front. At this time, the partition wall engaging portion 151 of the base body engages with the partition wall 64 to position the exterior body 22 in the left-right direction and functions as a slide guide for guiding the exterior body 22. When the exterior body 22 is slid along the guide, the left side surface of the main body portion 171 engages with the right wall surface of the housing recess 60 on the left side of the partition wall 64, and the rail engagement portion 172 engages with the slide rail 162. When the outer body 22 is further slid and the rib flange of the partition wall 64 abuts on the operation member 180, the right wall surface of the partition wall 64 is elastically deformed so as to open obliquely upward, and the operation member 180 is moved over to move the lever insertion portion. 163. Then, by sliding and abutting until each rear end portion of the exterior body 22 comes into contact with the standing wall surface of the base body 21, a screw is screwed into the screw boss of the exterior body from the rear surface side of the base body 21 and tightened. The ball removal mechanism BM1b is assembled to form the lower ball dish structure 20 having the ball removal mechanism.

  When the ball removal mechanism BM1b is assembled, the valve element 170 is accommodated and supported by the valve element accommodating portion 161 below the partition wall 64 so as to be horizontally displaceable in the front-rear direction, and is always urged forward by the coil spring 147 to operate. The restriction position where the member 180 abuts against the front end surface of the slide range restriction portion 152, specifically, the main body portion 171 and the shutter portion 174 of the valve body 170 are held at the closed position where the entire opening is closed on the back side of the ball outlet 24. (See FIG. 16). Accordingly, the game balls paid out to the lower ball tray 23 are regulated to flow down by the valve body 170 in the closed position and stored in the lower ball tray 23.

In order to perform the ball removal operation, the operation portion 185 of the operation member 180 is pressed backward against the urging force of the coil spring 147. Then, the valve body 170 slides backward in the valve body accommodating portion 161, the main body portion 171 and the shutter portion 174 move rearward, and the ball outlet 24 is opened. When the operating member 180 is pressed to the restricting position abutting the rear end surface of the sliding range restricting portion 152, in the open position the body portion 171 and the shutter 174 of the valve body 170 opens the entire opening of the sphere vent port 24 (Refer to the two-dot chain line in FIG. 16). Accordingly, the game balls stored in the lower ball tray 23 flow down to the ball box BB prepared below through the ball outlet 24 and the discharge port 25.

  On the lower side of the ball outlet 24, the forward transfer prevention wall 105 is located in front of the ball outlet 24, the right side transfer prevention wall 106 is located on the right side of the ball outlet 24, and the function of the transfer prevention wall is located on the left side of the ball outlet 24. A rear transfer prevention wall 175 is disposed at the front end of the slide rail 162 and the shutter portion 174 having the same. Therefore, when the valve body 170 is opened, the lower periphery of the ball outlet 24 is surrounded by these transfer-in prevention walls to form a duct-like discharge path, and the game flows down from the ball outlet 24 to the discharge port 25. A sphere does not enter between the base body 21 and the exterior body 22.

  Also, in the ball removal mechanism BM1b, similarly to the ball removal mechanism BM1a, the coil spring 147 is supported by the spring support column 107 that supports the inner periphery of the coil spring 147 and the spring housing portion 127 that supports the outer periphery, and A spring accommodating portion 127 is formed inside the main body of the valve body 170. For this reason, in the open position of the valve body 170, the spring column 107 is received in the valve body 170 (spring accommodating portion 127) moved rearward, and substantially the entire coil spring 147 is accommodated in the valve body 170. . Therefore, it is possible to configure a ball removal mechanism having a large opening size with a compact configuration.

  When the ball removal operation is finished, the pressing force for holding the operation unit 185 in the open position may be weakened. When the forward pressing force is weakened, the coil spring 147 self-resets in the extending direction due to the elastic force accumulated in the coil spring 147, and the valve body 170 slides forward in the valve body accommodating portion 161, The part 171 and the shutter part 174 close the ball outlet 24. When the operation member 180 comes into contact with the front end surface of the slide range restricting portion 152, the forward movement of the valve body 170 is restricted, and the main body portion 171 and the shutter portion 174 hold the ball outlet 24 while maintaining a predetermined urging force. Is held in a closed position that closes the entire opening on the back side (see FIG. 12).

  As described above, in the ball removal mechanism BM1b of the present configuration, the operation unit 185 for opening and closing the ball removal port 24 is provided on the left side of the lower ball tray 23 so as to be slidable in the front-rear direction. The player can easily remove the ball with the left hand while turning the firing handle 14 and can easily be a player who has a close contact between the lower ball tray structure 20 and the abdomen. Ball removal operation can be performed.

  Further, since the operation unit 185 is provided on the upper surface side of the lower ball tray structure 20 so as to be slidable in the front-rear direction, the operation unit 185 can be operated even if the player accidentally hits the front surface of the lower ball tray structure 20. There is no possibility that the ball outlet 24 is opened due to an erroneous operation in the opening direction, and a situation in which game balls are scattered around does not occur. In addition, the main component of the ball removal mechanism is configured by effectively using the lower region of the partition wall 64, and the operation unit 185 is disposed so as to protrude from the partition wall 64 toward the lower ball tray 23. Thus, it is possible to provide a ball removal mechanism with good operability. Further, since the lever insertion portion 163 through which the operation member 180 is inserted is formed on the side surface of the partition wall 64 on the side of the lower ball tray 23, it becomes a configuration in which tobacco ash, dust, and the like do not easily enter the inside of the ball removal mechanism. ing.

  Therefore, according to the ball removal mechanism BM1b described above, it is possible to effectively prevent scattering of the game ball due to an erroneous operation, and to provide a ball removal mechanism with good operability for the player.

And a valve body 220 that opens and closes the ball outlet 24, and an operation member 230 that performs a displacement operation of the valve body 220. The operation portion 235 of the operation member 230 is located on the left side of the lower ball tray 23. It is provided on the bottom side of the lower ball tray structure 20 so as to be slidable in the front-rear direction, and is configured such that when the operation unit 235 is slid, the valve body 220 is horizontally displaced to open and close the ball outlet 24.

  The lower ball tray structure 20 includes a base body 21 that forms the base of the lower ball tray structure 20 and an exterior body 22 that forms the outer shell of the lower ball tray structure 20 in the same manner as the lower ball tray structure described above. Is mounted so as to cover the exterior body 22 from the front of the base body 21, and the exterior body 22 is screwed from the rear surface side of the base body 21 to form an integrated assembly.

  The base body 21 is integrally formed with a lower ball tray 23 having a deep bottom surface that is loosely inclined to the front and left to open the upper surface and is vertically formed on the left front portion at the lower end of the inclined surface from the bottom surface to the left side wall. A ball outlet 24 that communicates is formed as an opening.

  A partition wall engaging portion 201 that is detachable in the front-rear direction in alignment with the inner shape of the partition wall 64 formed in the exterior body 22 is provided on the upper left side of the lower ball tray 23. On the lower surface side of the lower ball tray 23, a right side guide wall 206 that is located on the right side of the ball outlet 24 and protrudes downward and engages with the right side transfer prevention wall 216 of the exterior body 22 is provided. In addition to functioning as a guide wall that guides the right side transfer-in prevention wall 216 when the exterior body 22 is mounted, a guide groove that guides the tip of the shutter unit 224 is formed in cooperation with the right-side transfer-in prevention wall 216.

  The exterior body 22 is formed in the shape of an outer shell covering the top and bottom and the front surface of the base body 21 excluding the housing recess 60 (80) of the ashtray structure AT and the upper opening surface of the lower ball tray 23 as a whole. On the upper surface side of the exterior body 22, a rib flange that engages with the upper edge flange surface of the lower ball dish 23 is formed at the lower part of the right side wall of the partition wall 64, and the lower region of the partition wall 64 and the lower ball dish are formed on the lower side thereof. The opening part which connects the 23 side to right and left is formed.

  On the bottom surface side of the outer package 22, there is formed an opening 25 having a larger opening width than the ball outlet 24 on the lower ball tray side and communicating with the upper and lower sides and located below the ball outlet 24 in the assembled state. Has been. At the periphery of the discharge port 25, a plurality of forward transfer prevention ribs 215 are erected upward at an arrangement pitch narrower than the ball diameter of the game ball in front of the discharge port 25, and along the right edge of the opening of the discharge port 25. A rightward transfer prevention wall 216 is formed. The forward transfer prevention ribs 215 are arranged at a pitch narrower than the ball diameter of the game ball, so that the game ball flowing down from the outlet 24 enters the front area between the bottom surface of the lower ball tray 23 and the exterior body 22. In the closed posture of the valve body 220, it engages and supports the rear transfer prevention wall 225 at the front end of the shutter portion to form a closed side regulating portion that defines the movement range of the valve body 220. Further, the right side transfer prevention wall 216 prevents the game ball flowing down from the ball outlet 24 from entering the right side region between the bottom surface of the lower ball tray 23 and the outer body 22, and the front end portion of the shutter portion 224. It also functions as a support rail that slidably supports.

  Below the partition wall 64, two slide rails 212, 212 projecting inward from the front wall surface and bottom surface of the exterior body 22 and extending in the front-rear direction are formed side by side in parallel. The left and right slide rails 212 are formed in an L-shaped frame shape by connecting the front wall surface and the bottom surface to improve the rigidity of the exterior body 22, and the right slide rail is aligned with the opening left edge of the discharge port 25. 24 is formed so as to be close to the upper edge of the opening, and the game ball flowing down from the ball outlet 24 is guided to the discharge port 25 so that the game ball does not enter the left side region between the base body 21 and the exterior body 22. It is like that. That is, the slide rail 212 has a function as a reinforcing frame of the exterior body 22 in addition to a function as a slide rail that supports the valve body 220 so as to be slidable back and forth, and the left side transfer prevention wall 116 and the left side slide transfer. It has a structure that combines the function of the prevention wall 126 (see FIG. 8 and the like).

  On the bottom surface side of the exterior body 22, a concave operation portion protection groove 214 is formed in which the front portion of the bottom surface connecting the left and right slide rails 212, 212 is offset upward and opens downward. A slit-like operation portion guide hole 213 extending in the direction is formed. The operation portion guide hole 213 is formed to have a slit width that is slightly larger than the thickness of the operation member 230, and allows the operation portion 235 of the operation member 230 to be moved forward and backward to the operation portion protection groove 214, The rear end position of the part guide hole 213 is formed in accordance with the open position of the valve body 220, and when the operation part 235 is pushed rearward to reach the open position, it engages with the vertical end surface of the operation part 235. An open side restricting portion that restricts the backward movement and defines the valve body 220 at the open position is formed.

  Then, when the exterior body 22 is covered and engaged from the front of the base body 21, below the partition wall 64, the right wall surface of the housing recess 60, the left wall surface of the lower ball tray 23, the partition wall engaging portion 201, and A valve body accommodating portion 211 having a trapezoidal cross-sectional shape extending in the front-rear direction and surrounded by the slide rail 212 is formed. A columnar spring column 207 having an outer diameter somewhat smaller than the inner diameter of the coil spring 247 is formed on the standing wall surface of the base body 21 at the inner part of the valve body accommodating portion 211 so as to protrude forward.

  On the other hand, the valve body 220 includes a hollow block-shaped main body portion 221 formed in accordance with the cross-sectional shape of the valve body housing portion 211, a shutter portion 224 formed to extend to the right below the main body portion 221, and a main body. The operation member 230 formed to extend forward from the front surface of the portion 221 is mainly used, and is molded using the same resin material as that of the valve body 120 described above.

  On the lower surface of the main body 221, concave rail engaging portions 222, 222 that can be freely engaged with and disengaged from the left and right slide rails 212, 212 are formed to extend back and forth, and the valve body 220 is accommodated in the valve body accommodating portion 211. Sometimes, the rail engaging portion 222 is engaged with and supported by the slide rail 212, and the main body portion 221 is engaged with the upper and left and right wall surfaces of the valve body accommodating portion 211 so as to be slidable in the front-rear direction. It is like that.

  At the center of the inside of the main body 221, there is a cylindrical housing part that has an inner diameter somewhat larger than the outer diameter of the coil spring 247 and opens rearward, and an outer diameter that is somewhat smaller than the inner diameter of the coil spring 247. Thus, a spring accommodating portion 227 made up of a spring support portion protruding into the cylindrical accommodating portion is formed. The height of the spring column is set so that the total of the height of the spring column and the height of the spring column 207 on the base body side is smaller than the depth of the cylindrical housing.

  The shutter part 224 is formed in a plate shape that protrudes to the right side from the lower part of the main body part 221 in accordance with the height position of the lower surface side of the ball outlet 24, and has a protruding width in the left-right direction and a dimension in the front-rear direction. It is formed slightly larger than the opening width and opening size of the mouth 24. On the other hand, the ball outlet 24 is formed in front of the lower ball tray 23, and the dimension from the opening rear edge of the ball outlet 24 to the standing wall surface of the base body 21 is set to be larger than the longitudinal dimension of the shutter portion 224. Yes.

  Therefore, when the valve body 220 is positioned at the closed position, the shutter portion 224 closes the entire opening of the ball outlet 24, and when the valve body 220 is positioned at the open position, the rear end of the shutter portion 224 is The ball outlet 24 can be completely opened without contacting the standing wall surface of the base body 21. A rearward transfer prevention wall 225 extending downward is formed at the front end of the shutter portion 224, and a game ball that flows down from the ball outlet 24 when the shutter portion 224 is opened is formed on the bottom surface of the lower ball tray 23, the exterior body 22, and the like. It is designed not to enter the rear area.

  The operation member 230 is formed in a plate shape having a triangular shape in a side view, standing upright at the center of the front surface of the main body portion 221 and extending forward, and an operation portion 235 having a rearward vertical end surface extending downward. ing. The operation member 230 is arranged so that the operation portion 235 at the tip is disposed in the operation portion protection groove 214 through the operation portion guide hole 213 and does not protrude below the bottom surface of the exterior body 22 in a state where the valve body 220 is assembled. In addition, when the valve body 220 is in the closed position, the front end of the operation portion 235 slightly protrudes from the front surface of the exterior body 22 and is easily disposed with the finger, and the operation portion 235 is pushed rearward to be the valve body. When 220 reaches the open position, the vertical end surface of the operation portion 235 is configured to engage with the rear end of the operation portion guide hole 213 so that rearward movement is restricted.

  The members configured as described above are assembled between the base body 21 and the exterior body 22 to form the ball removal mechanism BM2. Assembling is performed by inserting the valve body 220 obliquely from the opening on the lower ball tray side of the exterior body 22 and inserting the operation portion 235 into the operation portion guide hole 213 and engaging the rail engagement portion 222 with the slide rail 212. Then, the front end of the shutter portion 224 is engaged with and supported by the right side transfer-in prevention wall 216. Thereby, the valve body 220 is supported by the exterior body 22 so as to be slidable in the front-rear direction.

  Next, one end of the coil spring 247 is supported on the spring support 207 of the base body (or the spring accommodating portion 227 of the valve body), and is mounted so that the exterior body 22 is covered from the front of the base body 21. At this time, the partition wall engaging portion 201 of the base body is engaged with the partition wall 64 of the exterior body, and the right side guide wall 206 of the base body is engaged with the right side transfer prevention wall 216 of the exterior body, so that the exterior body 22 is engaged. Is positioned in the left-right direction and functions as a slide guide for guiding the exterior body 22. In this sliding process, the other end side of the coil spring 247 is supported on the spring accommodating portion 227 on the back surface of the valve body (or 207 on the spring support on the front surface of the base body). Thus, the coil spring 247 is supported between the spring support 207 and the spring accommodating portion 227 so as to be elastically movable back and forth.

  Then, by sliding and abutting until each rear end portion of the exterior body 22 comes into contact with the standing wall surface of the base body 21, a screw is screwed into the screw boss of the exterior body from the rear surface side of the base body 21 and tightened. The ball removal mechanism BM2 is assembled to form the lower ball dish structure 20 having the ball removal mechanism.

  When the ball removal mechanism BM2 is assembled in this way, the valve body 220 is accommodated and supported by the valve body accommodating portion 211 below the partition wall 64 so as to be horizontally displaceable in the front-rear direction, and is always urged forward by the coil spring 247. A closed position in which the rear transfer prevention wall 225 at the front end of the shutter part abuts against the front transfer prevention rib 215 and is restricted from movement, and the main body part 221 and the shutter part 224 of the valve body 220 close the entire opening on the back side of the ball outlet 24. (See FIGS. 24 and 25). Accordingly, the game balls discharged from the lower ball tray discharge passage to the lower ball tray 23 through the discharge bucket 18 and the lower outlet 17 are regulated to flow down by the valve body 220 in the closed position and stored in the lower ball tray 23. . The operation portion 235 of the operation member 230 is positioned in front of the operation portion protection groove 214 and its front end slightly protrudes to the front side of the exterior body 22 and is easily disposed with a finger. Note that the amount of forward protrusion of the operation unit 235 is less than half of the ball diameter of the game ball, so that even when the operation unit 235 is accidentally brought into contact with the operation unit 235, the ball is not removed.

In order to perform the ball removal operation, a finger is put on the operation unit 235 and the operation member 230 is pressed backward against the urging force of the coil spring 247. Then, the valve body 220 slides backward in the valve body accommodating portion 211, the main body portion 221 and the shutter portion 224 move rearward, and the ball outlet 24 is opened. Then open the vertical end surface of the operating portion 235 backward is pressed to a regulating position abutting the rear end surface of the operating portion guide hole 213, the main body portion 221 and the shutter 224 of the valve body 220 is the entire opening of the sphere vent port 24 The game balls stored in the lower ball tray 23 flow down to the ball box BB prepared below through the ball discharge port 24 and the discharge port 25 (see FIG. 27).

  On the lower side of the ball outlet 24, a forward transfer prevention rib 215 is provided in front of the ball outlet 24, a right side transfer prevention wall 216 is provided on the right side of the ball outlet 24, and a function of a transfer prevention wall is provided on the left side of the ball outlet 24. A rear transfer prevention wall 225 is disposed at the front end of the slide rail 212 and the shutter portion 224. For this reason, when the valve body 220 is opened, the lower periphery of the ball outlet 24 is surrounded by these transfer-in prevention walls to form a duct-like discharge path, and the game flows down from the ball outlet 24 to the discharge port 25. A sphere does not enter between the base body 21 and the exterior body 22.

  In addition, the front and rear of the coil spring 247 are supported by the spring support 207 that supports the inner periphery of the coil spring 247 and the spring accommodating portion 227 that supports the inner and outer periphery of the coil spring 247, and the height of the front and rear spring posts is determined by the spring. The spring housing portion 227 is formed inside the main body of the valve body 220 and is formed smaller than the depth of the housing portion 227. For this reason, in the open position of the valve body 220, the spring column 207 is received in the valve body 220 (spring accommodating portion 227) moved rearward, and substantially the entire coil spring 247 is accommodated in the valve body 220. . Therefore, it is possible to configure a ball removal mechanism having a large opening size with a compact configuration.

When the ball removal operation is finished, the pressing force for holding the operation unit 235 in the open position may be weakened. When the backward pressing force is weakened, the elastic force accumulated in the coil spring 247 causes the coil spring 247 to self-reset in the extending direction, and the valve body 220 slides forward in the valve body housing portion 211 to move the main body. The part 221 and the shutter part 224 close the ball outlet 24. Then, when the rearward transfer prevention wall 225 at the front end of the shutter part comes into contact with the forward transfer prevention rib 215, the forward movement of the valve body 220 is restricted, and the main body part 221 and the shutter part 224 are ball-shaped while maintaining a predetermined urging force. It is held in a closed position that closes the entire opening on the back side of the outlet 24 (see FIGS. 24 and 25).

  As described above, in the ball removal mechanism BM2, the operation portion 235 for opening and closing the ball removal opening 24 is provided on the left side of the lower ball tray 23 so as to be slidable in the front-rear direction. The ball removal operation can be easily performed with the left hand while rotating 14.

  Further, since the operation portion 235 is provided in the operation portion protection groove 214 on the lower surface side of the lower ball tray structure 20 so as to be slidable in the front-rear direction, when the player stands up or sits down from the seat, Even if it hits the front of the lower ball tray structure 20 when trying to take a ball box left in a pachinko machine, the operation unit 235 is erroneously operated in the opening direction and the ball outlet 24 is opened. There is no such a situation that the game balls are scattered around. Furthermore, the main component of the ball removal mechanism is configured by effectively using the lower region of the partition wall 64, and the operation unit 235 is disposed on the lower surface side of the structure below the partition wall. A ball removal mechanism with good operability can be provided. In addition, since the operation portion guide hole 213 through which the operation member 230 is inserted is formed on the lower surface side of the ball tray structure 20, the structure can effectively prevent the invasion of tobacco ash, dust, and the like.

  Therefore, according to the ball removal mechanism BM2 described above, it is possible to effectively prevent scattering of the game ball due to an erroneous operation, and to provide a ball removal mechanism with good operability for the player.

(Ball removal mechanism BM3)
Next, the ball removal mechanism BM3 of the third configuration form will be described with reference to each of FIGS.

  On the bottom surface side of the outer package 22, there is formed an opening 25 having a larger opening width than the ball outlet 24 on the lower ball tray side and communicating with the upper and lower sides and located below the ball outlet 24 in the assembled state. Has been. A right side transfer prevention wall 316 is formed on the right side of the discharge port 25 along the opening right edge of the discharge port 25, and the game ball flowing down from the ball discharge port 24 is placed on the bottom surface of the lower ball tray 23 and the exterior body. 22, and also functions as a support rail that slidably supports the distal end portion of the shutter portion 324.

  Below the partition wall 64, two slide rails 312 and 312 projecting inward from the front wall surface and bottom surface of the exterior body 22 and extending in the front-rear direction are formed side by side in parallel. The left and right slide rails 312 are formed in an L-shaped frame connecting the front wall surface and the bottom surface to improve the rigidity of the exterior body 22, and the right slide rail matches the opening left edge of the discharge port 25 with a ball outlet. 24 is formed so as to be close to the upper edge of the opening, and the game ball flowing down from the ball outlet 24 is guided to the discharge port 25 so that the game ball does not enter the left side region between the base body 21 and the exterior body 22. It is like that. That is, the slide rail 312 has a function as a reinforcing frame of the exterior body 22 in addition to a function as a slide rail that supports the valve body 320 so as to be slidable back and forth, and the left side intrusion prevention wall 116 and the left side slide in. It has a structure that combines the function of the prevention wall 126 (see FIG. 8 and the like).

  On the front side of the exterior body 22, the front wall surface between the left and right slide rails 312, 312 is recessed to form a concave operation portion protection groove 314 extending vertically, and a slit-like operation portion guide is formed at the center of the bottom surface of the groove. A hole 313 is formed. The operation portion guide hole 313 has a slit width somewhat larger than the thickness of the operation portion 335 of the operation member 330 and is formed in the vertical direction, and leads the operation portion 335 to the operation portion protection groove 314. The operation unit 335 is guided to swing up and down.

  When the exterior body 22 is covered and engaged from the front of the base body 21, the right wall surface of the housing recess 60, the left wall surface of the lower ball tray 23, the partition wall engaging portion 301, and the slide rail are provided below the partition wall 64. A valve body accommodating portion 311 having a trapezoidal cross-sectional view extending in the front-rear direction surrounded by 312 is formed. A columnar spring column 307 having an outer diameter somewhat smaller than the inner diameter of the coil spring 347 is formed on the standing wall surface of the base body 21 at the back of the valve body housing portion 311 so as to protrude forward.

  On the other hand, the valve body 320 includes a hollow block-shaped main body portion 321 formed in accordance with the cross-sectional shape of the valve body housing portion 311, a shutter portion 324 formed to extend to the right side below the main body portion 321, A pair of left and right link arms 326 formed so as to extend forward from the front surface of the portion 321 are mainly used, and are molded using the same resin material as that of the valve body 120 described above.

  Recessed rail engaging portions 322 and 322 detachably engageable with the left and right slide rails 312 and 312 are formed on the lower surface of the main body portion 321 so that the valve body 320 is accommodated in the valve body accommodating portion 311. Sometimes the rail engaging portion 322 is engaged with and supported by the slide rail 312, and the main body portion 321 is engaged with the upper and left and right wall surfaces of the valve body housing portion 311 and is supported slidably in the front-rear direction. It is like that.

  In the center of the main body 321, a cylindrical housing part that has an inner diameter somewhat larger than the outer diameter of the coil spring 347 and opens rearward, and an outer diameter that is somewhat smaller than the inner diameter of the coil spring 347. Thus, a spring accommodating portion 327 including a spring support portion protruding into the cylindrical accommodating portion is formed. The height of the spring strut portion is set so that the sum of the height of the spring strut portion on the spring accommodating portion side and the height of the spring strut 307 on the base body side is smaller than the depth dimension of the cylindrical accommodating portion. ing.

  The shutter part 324 is formed in a plate shape that protrudes rightward from the lower part of the main body part 321 according to the height position on the lower surface side of the ball outlet 24, and the protruding width in the left-right direction and the dimension in the front-rear direction are the same. It is formed slightly larger than the opening width and opening size of the mouth 24. On the other hand, the ball outlet 24 is formed in front of the lower ball tray 23, and the dimension from the opening rear edge of the ball outlet 24 to the standing wall surface of the base body 21 is set to be larger than the longitudinal dimension of the shutter portion 324. Yes.

  Therefore, when the valve body 320 is positioned at the closed position, the shutter portion 324 closes the entire opening of the ball outlet 24, and when the valve body 320 is positioned at the open position, the rear end of the shutter portion 324 is The ball outlet 24 can be completely opened without contacting the standing wall surface of the base body 21. A rearward transfer prevention wall 325 extending downward is formed at the front end of the shutter portion 324, and a game ball that flows down from the ball outlet 24 when the shutter portion 324 is opened is attached to the bottom surface of the lower ball tray 23, the exterior body 22, and the like. It is designed not to enter the rear area.

  The pair of left and right link arms 326 are formed to extend obliquely downward and forward from the lower front surface of the main body portion 321, and the tip end side thereof extends downward and is formed in a hook shape. The distance between the inner surfaces of the left and right link arms is set to be slightly larger than the thickness of the swing arm 336 in the operation member 330, and the swing arm 336 is formed between the left and right link arms 326 and 326. In addition, a shaft support hole 326h into which the arm connection pin 346 is inserted is formed at the front end portion of each link plate in alignment.

  The operation member 330 includes a flat plate-like main body plate portion 331 and a boss portion 332 formed in a disk flange shape thicker than the main body plate portion at the end of the main body plate portion 331. Similarly, it is integrally molded by molding means such as injection molding using a thermoplastic resin material such as ABS resin.

  The main body plate portion 331 is generally formed in a fan shape centered on the boss portion 332, and one side edge side thereof is extended into a lever having an arcuate tip shape to form an operation portion 335, and the other side edge side is formed. Similarly, a swing arm portion 336 is formed. A bearing hole 332h into which the pivot pin 342 is fitted is formed at the center of the boss part 332, and a pin engaging hole 336h into which the arm connecting pin 346 is inserted is formed at the tip of the swing arm part 336 in the extending direction of the arm. It is formed in a long hole shape.

  The relative angle and the length of each arm of the operation unit 335 and the swing arm unit 336 are such that the boss portion 332 is pivotally connected to the support bracket 302 by the pivot pin 342, and the operation portion 335 is within the height range of the operation portion protection groove 314. When the rocking arm 336 is swung in the up-and-down direction, the rocking arm portion 336 that is swung along with this moves in the front-rear direction inside the exterior body 22 and moves in the front-rear direction of the pin engagement hole 336 h at this time. Is set so as to satisfy a stroke necessary for sliding the shutter unit 324 between the closed position and the open position.

  In the ball removal mechanism BM3, the relative angle between the operation portion 335 and the swing arm portion 336 is set to approximately 90 degrees, the operation portion 335 is disposed forward, the swing arm portion 336 is disposed below, and the swing support point By providing the support bracket 302 formed above the interior of the exterior body 22, the arm length of the swinging arm 336 extending downward is secured, and thereby the swinging operation angle of the operation unit 335 is set to the center from the upper end of the operation unit protection groove 314. The shutter unit 324 is configured to satisfy a necessary stroke for sliding the shutter unit 324 between the closed position and the open position while suppressing the angle range to a lower level of about 60 degrees.

  The long pin-shaped pin engaging hole 336h formed at the tip of the swing arm 336 has a width dimension substantially the same as the shaft diameter of the arm connecting pin 346, while the length dimension of the pin engaging hole 336h is the same as that of the operating portion 335. The tip of the swing arm 336 is formed to be larger than the amount of displacement in the vertical direction when it is swung up and down. For this reason, when the pin engaging hole 336h of the swing arm and the shaft support hole 326h of the link arm are connected by the arm connecting pin 346 and the operation member 330 is swung, the operation member 330 and the valve body 320 are connected. The operating force is transmitted to the valve body by loosely fitting in the front-rear direction, and the arm connecting pin 346 moves up and down in the pin engagement hole with respect to the vertical displacement accompanying the swing of the swing arm 326. Thus, the relative displacement of the swing arm is allowed, and the valve body 320 is slid in the front-rear direction with a stroke corresponding to the swing angle of the operation member 330.

  The operation unit 335 is disposed in the operation unit protection groove 314 through the operation unit guide hole 313 in a state where the valve body 320 and the operation member 330 are assembled, and the shutter unit 324 is in a closed position where the bulb outlet 24 is blocked. When it is located at the upper end of the operation portion protection groove 314 so as not to protrude from the front end of the exterior body 22 (see FIG. 37), the shutter portion 324 is in the open position where the ball outlet 24 is opened. The operation part protection groove 314 is positioned at the lower center of the operation part so as to be easily held (see FIG. 38).

  The ball removal mechanism BM3 is formed by assembling the valve body 320 and the operation member 330 configured as described above to the base body 21 and mounting the exterior body 22 so as to cover the exterior body 22 from the front. In the assembly, the boss portion 332 of the operating member is received between the left and right shaft support plates of the support bracket 302 in the base body 21, and the pivot pin 342 is inserted from one side of the support bracket 302 through the shaft support hole 302h and the bearing hole 332h. The E-ring is inserted into the ring groove on the distal end side of the pivot pin 342 that is inserted and protruded to the other side. As a result, the operation member 330 is pivotally connected to the support bracket 302, and the operation member 330 is supported by the support bracket 302 so as to be swingable within a plane orthogonal to the axis of the pivot pin 342.

  Next, the left and right link arms 326 of the valve body 320 are engaged with the distal end portion of the swing arm 336 of the operation member 330 so as to sandwich the left and right side surfaces of the swing arm, and from one side of the link arm 326. The arm connection pin 346 is inserted through the shaft support hole 326h and the pin engagement hole 336h, and the E ring is inserted into the ring groove on the tip side of the arm connection pin 346 protruding to the other side. Accordingly, the swing arm 336 and the link arm 326 are pin-engaged, and the valve body 320 is coupled so as to be relatively swingable within the same plane as the swing surface of the operation member 330.

  In this way, the valve body 320 connected to the operation member 330 is swung upward to engage and support the upper surface and the right side surface of the main body 321 with the lower edge of the partition wall engaging portion 301 and the left side surface of the lower ball tray 23. A coil spring 347 is fitted between the spring housing portion 327 on the valve body side and the spring support 307 on the base body side that face each other.

  And it mounts | wears so that the exterior body 22 may be covered from the front of the base body 21. FIG. At this time, the partition wall engaging portion 301 of the base body is engaged with the partition wall 64 of the exterior body, and the right side guide wall 306 of the base body is engaged with the right side transfer-in preventing wall 316 of the exterior body and the exterior body 22 is engaged. Is positioned in the left-right direction and functions as a slide guide for guiding the exterior body 22. In this sliding process, the rail engaging portion 322 formed on the lower surface side of the valve body 320 is engaged with the slide rail 312, and the main body portion 321 is supported by the valve body housing portion 311 so as to be slidable back and forth. The operating portion 335 protrudes into the lever accommodating portion 314 through the operating portion guide hole 313.

  Then, by sliding and abutting until each rear end portion of the exterior body 22 comes into contact with the standing wall surface of the base body 21, a screw is screwed into the screw boss of the exterior body from the rear surface side of the base body 21 and tightened. The ball removal mechanism BM3 is assembled to form the lower ball dish structure 20 having the ball removal mechanism.

  When the ball removal mechanism BM3 is assembled in this way, the valve element 320 is accommodated and supported by the valve element accommodating portion 311 below the partition wall 64 so as to be horizontally displaceable in the front-rear direction, and is always urged forward by the coil spring 347. A closed position in which the rear transfer prevention wall 325 at the front end of the shutter part abuts against the front transfer prevention wall 305 and movement is restricted, and the main body part 321 and the shutter part 324 of the valve body 320 close the entire opening on the back side of the ball outlet 24. (See FIGS. 36 and 37). Accordingly, the game balls discharged to the lower ball tray 23 from the lower ball tray discharge passage via the discharge bucket 18 and the lower outlet 17 are regulated to flow down by the valve body 320 in the closed position and stored in the lower ball tray 23. .

  At this time, the operating member 330 has a swing angle position defined by the position of the swing arm 336 connected by the link arm 326 of the valve body 320 and the arm connecting pin 346, and the operation portion 335 is moved from the front end of the exterior body 22. Is also positioned at the upper end of the operation portion protection groove 314 without protruding.

  In order to perform the ball removal operation, a finger is put on the operation unit 335 and pressed downward, and the operation unit 335 is swung downward against the urging force of the coil spring 347. Then, the valve body 320 is pressed rearward by the swing arm 336 swinging rearward via the arm connecting pin 346, and the valve body 320 moves in the valve body housing portion 311 with a stroke corresponding to the swing angle of the operation member 330. The main body portion 321 and the shutter portion 324 are moved rearward and the ball outlet 24 is opened.

  When the operation part 335 is swung until it is located at the lower center of the operation part protection groove 314, the main body part 321 and the shutter part 324 of the valve body 320 are disposed at an open position where the entire opening of the ball outlet 24 is opened. Then (see FIG. 38), the game balls stored in the lower ball tray 23 flow down to the ball box BB prepared below through the ball outlet 24 and the outlet 25. Note that the lower end of the operation portion guide hole 313 may be formed to match this open position, and the swing angle position of the operation portion 335 may be defined.

  On the lower side of the ball outlet 24, a forward transfer prevention wall 305 is provided in front of the ball outlet 24, a right side transfer prevention wall 316 is provided on the right side of the ball outlet 24, and a transfer prevention wall is provided on the left side of the ball outlet 24. A rear transfer prevention wall 325 is disposed at the front end of the slide rail 312 and the shutter portion 324 having the above-described structure. For this reason, when the valve body 320 is opened, the lower periphery of the ball outlet 24 is surrounded by these transfer-in prevention walls to form a duct-shaped discharge path, and the game flows down from the ball outlet 24 to the discharge port 25. A sphere does not enter between the base body 21 and the exterior body 22.

  Further, the front and rear of the coil spring 347 are supported by the spring support 307 that supports the inner periphery of the coil spring 347 and the spring housing portion 327 that supports the inner and outer periphery of the coil spring 347, and the height of the front and rear spring posts is determined by the spring. It is formed smaller than the depth dimension of the accommodating portion 327, and the spring accommodating portion 327 is formed inside the main body of the valve body 320. For this reason, in the open position of the valve body 320, the spring column 307 is received in the valve body 320 (spring accommodating portion 327) moved rearward, and substantially the entire coil spring 347 is accommodated in the valve body 320. . Therefore, it is possible to configure a ball removal mechanism having a large opening size with a compact configuration.

  When the ball removal operation is finished, the pressing force for holding the operation unit 335 in the open position may be weakened. When the downward pressing force is weakened, the coil spring 347 self-resets in the extending direction due to the elastic force accumulated in the coil spring 347, and the valve body 320 slides forward in the valve body housing portion 311. The part 321 and the shutter part 324 close the ball outlet 24. As a result, the operating member 330 connected by the arm connecting pin 346 is swung according to the forward movement of the valve body 320, and the operating portion 335 is swung upward at a swing angle according to the amount of movement of the valve body 320. Is done.

  When the rearward transfer prevention wall 325 at the front end of the shutter part comes into contact with the forward transfer prevention wall 305, the forward movement of the valve body 320 is restricted, and the main body part 321 and the shutter part 324 are ball-shaped while maintaining a predetermined urging force. The operation portion 335 is disposed at the upper end portion of the operation portion protection groove 314 while being held at a closed position where the entire opening is closed on the back side of the outlet 24. (See FIG. 37).

  As described above, in the ball removal mechanism BM3, the operation unit 335 for opening and closing the ball removal port 24 is provided on the left side of the lower ball tray 23 so as to be swingable in the vertical direction. The ball removal operation can be easily performed with the left hand while the handle 14 is rotated.

  In addition, the operation unit 335 is provided on the front side of the lower ball tray structure 20 so as to be swingable in the vertical direction, and the operation unit 335 is located from the front end of the lower ball tray structure 20 in a state where the ball outlet 24 is closed. Is also configured to be disposed in the rear operation portion protection groove 314. For this reason, when a player stands up from a seat or sits down, or when he or she is looking sideways to take a ball box left in an adjacent pachinko machine, the player hits the front of the lower ball tray structure 20. However, the operation unit 335 is not erroneously operated in the opening direction and the ball outlet 24 is not opened, and a situation in which the game balls are scattered around does not occur. Further, the main component of the ball removal mechanism is configured by effectively using the lower region of the partition wall 64, and the operation unit 335 is disposed on the front side of the structure in front of the partition wall 64. It is possible to provide a ball removal mechanism having a good operability with the configuration. In addition, since the operation portion guide hole 313 through which the operation member 330 is inserted is formed on the front surface side of the ball tray structure 20, it is configured such that tobacco ash, dust, and the like do not easily enter the ball removal mechanism. .

  Therefore, according to the ball removal mechanism BM3 described above, it is possible to effectively prevent the scattering of game balls due to an erroneous operation, and to provide a ball removal mechanism with good operability for the player.

The operation portion 435 of the operation member 430 is moved back and forth on the upper surface side of the lower ball tray structure 20 on the left side of the lower ball tray 23. The valve body 320 is horizontally displaced and opens and closes the ball outlet 24 when the operating portion 435 is swing-operated.

  A partition wall engaging portion 401 that can be engaged and disengaged in the front-rear direction in alignment with the inner shape of the partition wall 64 formed in the exterior body 22 is provided on the upper left side of the lower ball tray 23 of the base body 21. A support bracket 302 including a pair of left and right pivot plates that protrude downward is provided at the front end of the engagement portion 401. The distance between the inner surfaces of the left and right pivot plates is set to be slightly larger than the thickness dimension of the boss portion 432 of the operation member 430, and the pivot holes for inserting the pivot pins 342 into the center of each pivot plate. 302h is formed in the left-right alignment (see FIG. 32). A slit-like operation member receiving groove 403 having a groove width somewhat larger than the thickness of the main body plate portion 431 of the operation member and extending in the front-rear direction is formed in the support portion that connects the left and right pivot support plates in a front end open form. Is formed.

  On the other hand, on the upper surface side of the partition wall 64 in the exterior body 22, a slit-like operation portion guide hole 413 is formed to be aligned above the partition wall engaging portion 401. The operation portion guide hole 413 has a slit width somewhat larger than the thickness of the operation portion 435 of the operation member 430 and is formed in the front-rear direction, and leads the operation portion 435 to the upper surface side of the partition wall 64. The operation unit 435 is guided to swing back and forth.

  Below the partition wall 64, a pair of left and right slide rails 312, 312 are formed to protrude inward from the front wall surface and bottom surface of the exterior body 22, and when the exterior body 22 is covered and mounted in front of the base body 21. Further, below the partition wall 64, a valve body having a trapezoidal cross-sectional view extending in the front-rear direction is surrounded by the right wall surface of the housing recess 60, the left wall surface of the lower ball tray 23, the partition wall engaging portion 401, and the slide rail 312. A housing portion 311 is formed.

  The valve body 320 has a hollow block-shaped main body portion 321 formed in accordance with the cross-sectional shape of the valve body housing portion 311 as a base, and a pair of left and right rail engaging portions 322 formed on the lower surface side of the main body portion 321. A shutter 324 formed to extend rightward from the main body 321, a rearward transfer prevention wall 325 formed at the front end of the shutter 324, and a pair of left and right link arms 326 formed to extend forward from the front surface of the main body 321. The main body 321 includes a spring accommodating portion 327 formed inside. The contents of each part are as described above (see FIGS. 32 and 33).

  On the other hand, the operation member 430 includes a flat plate-like main body plate portion 431 and a boss portion 432 formed in a disk flange shape thicker than the main body plate portion at the approximate center of the main body plate portion 431. It is formed by molding means similar to the member 330. A part of the main body plate portion 431 extends in the outer peripheral direction around the boss portion to form a fan-like operation portion 435, and a lever-like swing arm portion 436 is formed on the opposite side across the boss portion 432. ing. A bearing hole 432h into which the pivot pin 342 is inserted is formed at the center of the boss part 432, and a pin engagement hole 436h into which the arm connecting pin 346 is inserted is formed at the tip of the swing arm part 436 in the extending direction of the arm. It is formed in a long hole shape.

  The arm length of the swing arm portion 436 and the angle of formation of the operation portion 435 are determined by pivoting the boss portion 432 to the support bracket 302 with the pivot pin 342 and swinging the operation portion 435 back and forth on the upper surface side of the partition wall 64. When this occurs, the swinging arm portion 436 swinging along with this moves in the front-rear direction inside the exterior body 22, and the amount of movement (swinging in the front-rear direction of the pin engagement hole 436h at this time) Arm length × swing angle) is set so as to satisfy a stroke necessary for sliding the shutter unit 324 between the closed position and the open position.

  In the ball removal mechanism BM4, a support bracket 302 serving as a swing fulcrum is provided in the upper part of the exterior body 22, so that the arm length of the swing arm 436 extending downward is secured and a swing operation angle as small as about 60 degrees. Thus, the shutter unit 324 is configured to satisfy a necessary stroke for sliding movement between the closed position and the open position, and the operation unit 435 is formed in accordance with the swing operation angle.

  An elongated pin engaging hole 436h formed at the tip of the swing arm 436 has a width dimension substantially the same as the shaft diameter of the arm connecting pin 346, while the length dimension of the pin engaging hole 436h is the same as that of the operating portion 435. The tip of the swing arm 436 is formed to be larger than the amount of displacement in the vertical direction when it is swung back and forth. For this reason, when the pin engaging hole 436h of the swing arm and the shaft support hole 326h of the link arm are connected by the arm connecting pin 346 and the operation member 430 is swung, the operation member 430 and the valve body 320 are The operating force is transmitted to the valve body by loosely fitting in the front-rear direction, and the arm connecting pin 346 moves up and down in the pin engagement hole with respect to the vertical displacement accompanying the swing of the swing arm 326. Thus, the relative displacement of the swing arm is allowed, and the valve body 320 is slid in the front-rear direction with a stroke corresponding to the swing angle of the operation member 430.

  The operation portion 435 is disposed slightly protruding (about 2 to 5 mm) through the operation portion guide hole 413 to the upper surface side of the partition wall 64 in a state where the valve body 320 and the operation member 430 are assembled, and the shutter portion 324. Is located at the swing angle position indicated by a two-dot chain line in FIG. 40 when the shutter is closed, and the shutter portion 324 is at the open position where the ball outlet is opened. It is arranged at a swing angle position indicated by a solid line. Note that a flat knurled surface is formed on the outer peripheral surface of the operation portion 435 so that a swing operation in the front-rear direction can be easily performed.

  The ball removal mechanism BM4 is formed by assembling the valve body 320 and the operation member 430 configured as described above to the base body 21 and mounting the exterior body 22 from the front thereof. Assembling, the operation member 435 is received in the operation member receiving groove 403 of the base body 21, and the boss portion 432 is received between the left and right shaft support plates of the support bracket 302. The pivot pin 342 is inserted through 302h and the bearing hole 432h, and the E-ring is fitted into the ring groove on the distal end side of the pivot pin 342 protruding to the other side. As a result, the operation member 430 is pivotally connected to the support bracket 302, and the operation member 430 is supported by the support bracket 302 so as to be swingable within a plane orthogonal to the axis of the pivot pin 342.

  Next, the left and right link arms 326 of the valve body 320 are engaged with the distal end portion of the swing arm 436 of the operation member 430 so as to sandwich the left and right side surfaces of the swing arm, and from one side of the link arm 326. The arm connection pin 346 is inserted through the shaft support hole 326h and the pin engagement hole 436h, and the E ring is inserted into the ring groove on the distal end side of the arm connection pin 346 protruding to the other side. Accordingly, the swing arm 436 and the link arm 326 are pin-engaged, and the valve body 320 is coupled so as to be relatively swingable within the same plane as the swing surface of the operation member 430.

  In this way, the valve body 320 connected to the operation member 430 is swung upward to engage and support the upper surface and the right side surface of the main body 321 with the lower edge of the partition wall engaging portion 401 and the left side surface of the lower ball tray 23. A coil spring 347 is fitted between the spring housing portion 327 on the valve body side and the spring support 307 on the base body side that face each other.

  And it mounts | wears so that the exterior body 22 may be covered from the front of the base body 21. FIG. At this time, the partition wall engaging portion 401 of the base body is engaged with the partition wall 64 of the exterior body, and the right side guide wall 306 of the base body is engaged with the right side transfer-in preventing wall 316 of the exterior body, so that the exterior body 22 is engaged. Is positioned in the left-right direction and functions as a slide guide for guiding the exterior body 22 (see FIGS. 34 and 36). In this sliding process, the rail engaging portion 322 formed on the lower surface side of the valve body 320 is engaged with the slide rail 312 and the main body portion 321 is supported by the valve body housing portion 311 so as to be slidable back and forth, and the operation member 430. The operation portion 435 protrudes to the upper surface side of the partition wall 64 through the operation portion guide hole 413.

  Then, by sliding and abutting until each rear end portion of the exterior body 22 comes into contact with the standing wall surface of the base body 21, a screw is screwed into the screw boss of the exterior body from the rear surface side of the base body 21 and tightened. The ball removal mechanism BM4 is assembled to form the lower ball dish structure 20 having the ball removal mechanism.

  When the ball removal mechanism BM4 is assembled in this way, the valve element 320 is accommodated and supported by the valve element accommodating portion 311 below the partition wall 64 so as to be horizontally displaceable in the front-rear direction, and is always urged forward by the coil spring 347. A closed position in which the rear transfer prevention wall 325 at the front end of the shutter part abuts against the front transfer prevention wall 305 and movement is restricted, and the main body part 321 and the shutter part 324 of the valve body 320 close the entire opening on the back side of the ball outlet 24. (See FIGS. 36 and 37). Accordingly, the game balls paid out to the lower ball tray 23 from the lower ball tray payout passage are regulated to flow down by the valve body 320 in the closed position and stored in the lower ball tray 23.

  At this time, the operating member 430 has a swing angle position defined by the position of the swing arm 436 connected by the link arm 326 of the valve body 320 and the arm connecting pin 346, and the operation unit 435 is shown in FIG. Is slightly protruded from the upper surface of the partition wall 64 in the angle orientation shown in FIG.

  In order to perform the ball removal operation, a finger or hand is placed on the outer peripheral surface (knurled eye) of the operation unit 435 and pulled forward (forward), and is swung forward against the urging force of the coil spring 347. Then, the valve body 320 is pressed rearward by the swing arm 436 swinging rearward via the arm connection pin 346, and the valve body 320 moves in the valve body housing portion 311 with a stroke corresponding to the swing angle of the operation member 430. The main body portion 321 and the shutter portion 324 are moved rearward and the ball outlet 24 is opened.

  When the operation portion 435 is swung to the swing angle position indicated by the solid line in FIG. 40, the main body portion 321 and the shutter portion 324 of the valve body 320 are disposed at the open position where the entire opening of the ball outlet 24 is opened. The game balls stored in the lower ball tray 23 flow down to the ball box BB prepared below through the ball outlet 24 and the discharge port 25.

  On the lower side of the ball outlet 24, a forward transfer prevention wall 305 is provided in front of the ball outlet 24, a right side transfer prevention wall 316 is provided on the right side, a slide rail 312 having a function of a transfer prevention wall is provided on the left side, and a rear shutter portion. Since the rear transfer prevention wall 325 is disposed at the front end (see also FIG. 36), when the valve body 320 is opened, the lower periphery of the ball outlet 24 is surrounded by these transfer prevention walls. A game ball that forms a solid discharge path and flows down from the ball outlet 24 to the outlet 25 does not enter between the base body 21 and the exterior body 22.

  In addition, since the height of the spring strut before and after supporting the coil spring 347 is formed smaller than the depth dimension of the spring accommodating portion 327 and the spring accommodating portion 327 is formed inside the main body of the valve body 320, the valve The spring column 307 is received inside the valve body 320 in the open position where the body 320 has moved rearward, and substantially the entire coil spring 347 is housed inside the valve body 320. Therefore, it is possible to configure a ball removal mechanism having a large opening size with a compact configuration.

  When the ball removal work is finished, the holding force for holding the operation unit 435 in the open position may be weakened. When the holding force is weakened, the coil spring 347 self-resets in the extending direction by the elastic force accumulated in the coil spring 347, and the valve body 320 slides forward in the valve body housing portion 311 so that the main body portion 321 and The shutter unit 324 closes the ball outlet 24. Accordingly, the operation member 430 connected by the arm connection pin 346 is swung in accordance with the forward movement of the valve body 320, and the operation portion 435 is swung back at a swing angle corresponding to the movement amount of the valve body 320. Is done.

  When the rearward transfer prevention wall 325 at the front end of the shutter portion contacts the forward transfer prevention wall 305, the forward movement of the valve body 320 is restricted (see FIGS. 36 and 37), and a predetermined urging force is maintained. The main body portion 321 and the shutter portion 324 are held at the closed position that closes the entire opening on the back side of the ball outlet 24, and the operation portion 435 is disposed at the swing angle position indicated by the two-dot chain line in FIG.

  As described above, in the ball removal mechanism BM4, the operation unit 435 for opening and closing the ball removal opening 24 is located on the left side of the lower ball dish 23 and can be slid in the front-rear direction on the upper surface side of the lower ball dish structure 20. Therefore, a game in which the ball removal operation can be easily performed with the left hand while the firing handle 14 is rotated with the right hand, and the space between the lower ball tray structure 20 and the abdomen is closely attached. Even a person can easily perform the ball removal operation.

  In addition, since the operation unit 435 is provided on the upper surface side of the lower ball tray structure 20 so as to be swingable in the front-rear direction, when the player stands up or sits down from the seat or is left in the adjacent pachinko machine. When the player tries to take the ball box and turns to the side, even if it hits the front surface of the lower ball tray structure 20, the operation unit 435 is erroneously operated in the opening direction and the ball outlet 24 is opened. There is no such a situation that the game balls are scattered around. Furthermore, the main component of the ball removal mechanism is configured by effectively using the lower region of the partition wall 64, and the operation unit 435 is disposed on the upper surface of the partition wall 64. A good ball removal mechanism can be provided.

  Therefore, according to the ball removal mechanism BM4 described above, it is possible to effectively prevent scattering of the game ball due to an erroneous operation, and to provide a ball removal mechanism with good operability for the player.

  In the above, the configuration example in which the operation unit 435 protrudes from the upper surface side of the lower ball tray structure 20 has been described. However, the operation unit is disposed on the lower surface side of the lower ball tray structure 20, or It can also be arranged on the upper and lower surfaces of the dish structure 20 to constitute the ball removal mechanism of this configuration form. For example, a guide hole similar to the operation portion guide hole (313) described above is provided on the lower surface side of the exterior body 22, and the swing arm 436 is extended so that the lever-shaped operation portion is placed on the lower surface side of the lower ball tray structure 20. Or the swinging arm 436 is formed in a large fan shape and the operation part similar to the operation part 435 is protruded to the lower surface side of the lower ball dish structure 20, so that the lower ball dish structure 20 has a lower surface side. An operation unit can be provided, and in addition to the operation unit 435 described above, an operation unit on the lower surface side is provided, thereby forming a ball removal mechanism that can perform a ball removal operation on either the upper or lower operation unit. It is also possible.

Thus, a female screw portion for fixing the swing member 533 to the swing shaft 531 is formed in the direction perpendicular to the axis.

  The length of the collar portion including the swing arm portion at the front end (the dimension in the front-rear direction of the swing member 533) is the front end surface of the pivot boss 502 on the base body side when the exterior body 22 is attached and fixed to the base body 21. A swinging member 533 formed and fitted to the rear end surface of the bearing boss 512 on the exterior body side and fitted and supported by the swinging shaft 531 is vertically and horizontally (shafted) by the shaft support boss 502 and the bearing boss 512. Is positioned in the front-rear direction by a collar portion 533a sandwiched between the bosses 502 and 512, and is positioned in the angular direction by tightening the fixing screw 543.

  On the other hand, the front and rear swing arm portions 533b and 533b are formed in an arm shape projecting from the collar portion 533a in the same direction perpendicular to the axis, and an engagement pin 542 is received at the tip portion of the arm portion. The mating pin engaging grooves 533h and 533h are formed in the extending direction of the arm.

  Each pin engaging groove 533h is formed to have a width dimension substantially the same as the shaft diameter of the engaging pin 542, while its length dimension swings when the operating portion 535 is swung clockwise and counterclockwise. The tip of the arm portion 533b is formed to be larger than the amount of displacement that moves in the vertical direction. Therefore, when the front and rear pin engaging grooves 533h are engaged with the engaging pins 542 attached by connecting the front and rear shaft support flanges 522 of the valve body 520, the swing arm portion 533b is swung. The engaging groove 533h and the engaging pin 542 are fitted in the right and left direction without any backlash, and the operating force is transmitted to the valve body 520, and the arm tip portion is displaced in the vertical direction as the swinging arm portion 533b swings. On the other hand, the connecting pin 542 moves up and down in the pin engaging groove 533h to allow relative displacement of the swing arm portion, and slides the valve body 520 in the left-right direction with a stroke corresponding to the swing angle of the operation member 530. .

  The operation portion 535 is an operation knob including a knob portion 535a having knurled eyes formed on the outer peripheral surface and a hub portion 535b that receives the swing shaft 531. For example, a commercially available circular knob or polygonal knob is used. It is done. An arc-shaped operation display indicating the direction of the ball removal operation is provided on the front surface of the knob portion 535a, and a set screw 545 is screwed and fastened to the hub portion 535b to fix the operation member 535 to the swing shaft 531. Are formed in the direction perpendicular to the axis.

  The valve body 520 and the operation member 530 configured as described above are assembled to the exterior body 22, and the exterior body 22 on which each member is assembled is mounted so as to cover the front of the base body 21, thereby removing the ball removal mechanism BM5. Is formed. For assembly, first, the hub portion 535b of the operation portion 535 is fitted to the rear end of the swing shaft 531, the set screw 545 is tightened, and the screw tip portion is engaged with the flattening surface to fix the operation portion 535. Next, the swing shaft 531 is fitted into the bearing boss 512, and the collar portion 533 a of the swing member 533 is fitted to the swing shaft 531 protruding to the rear surface side of the exterior body 22, so that the operation member 535 and the swing member 533 Then, the bearing boss 512 is engaged so as to be clamped, and the tip end portion of the fixing screw 543 is engaged with the flattening surface in the middle of the swing shaft to be tightened, and the swing member 530 is fixed. As a result, the operation member 530 is assembled to the exterior body 22 and supported so as to be swingable around the swing shaft 531.

  Next, in a state where the swing arm portion 533b is swung to the right ball outlet 25 side, the valve body 520 is slid leftward from the ball outlet 25 side, and the engagement pin 542 is moved to the swing arm portion. Is engaged with the pin engaging groove 533h. Then, the operation unit 535 is rotated clockwise in front view (hereinafter the same is omitted), the swing arm 533b is swung clockwise, and the valve body 520 is slid to the left. At this time, the arm tip that moves downward with the swing of the swing arm 533b is received in the arm receiving groove 523, and the valve body 520 is slid to the left without any trouble, while the shutter 524 is removed from the ball. The right edge of the swing arm 533b abuts the chamfered portion of the upper end corner of the shutter 524 at the open position where the opening 24 is opened, and the valve body 520 slides to the left and the operating member 530 swings clockwise. Movement is restricted in the open position.

  With the shutter 524 retracted to the left in this way, the exterior body 22 assembled with each member is mounted and screwed so as to cover the front of the base body 21. At this time, the partition wall engaging portion 501 of the base body engages with the partition wall 64 of the exterior body, and the right side transfer-in prevention wall 506 of the base body engages with the right side guide wall 516 of the exterior body, and the exterior body 22. Is positioned in the left-right direction and functions as a slide guide for guiding the exterior body 22. Further, during this sliding process, the front end portion of the swing shaft 531 is fitted and supported by the base body side pivot boss 502, and the operation member 530 is positioned and supported between the pivot boss 502 and the bearing boss 512.

  Then, the operation portion 535 is rotated counterclockwise so that the shutter portion 524 is positioned at the closed position where the ball outlet 24 is closed, and one end of the tension spring 547 is screwed to the spring fixing boss 507 on the lower surface side of the exterior body. The other end side of the spring 547 is hooked on the hook 527 and stretched, whereby the ball removal mechanism BM5 is assembled, and the lower ball dish structure 20 having the ball removal mechanism is formed. 49 and 51, a spring case 548 that covers the tension spring 547 is provided on the lower surface side of the exterior body 22 so as to effectively prevent member damage and malfunction. .

  When the ball removal mechanism BM5 is assembled in this way, the valve body 520 is accommodated and supported by the valve body accommodating portion 511 below the partition wall 64 so as to be horizontally displaceable in the left-right direction, and is always urged rightward by the tension spring 547. Thus, the slide range restriction projection 528 at the right end of the shutter part is brought into contact with the right side transfer prevention wall 506 and restricted in movement, and the shutter part 524 is held at the closed position where the opening is closed on the back side of the ball outlet 24 (FIG. 48). And see FIG. Accordingly, the game balls discharged to the lower ball tray 23 from the lower ball tray discharge passage via the discharge bucket 18 and the lower outlet 17 are regulated to flow down by the valve body 520 in the closed position and stored in the lower ball tray 23. .

  In order to perform the ball removal operation, the operation portion 535 is picked and rotated clockwise, and the operation member 530 is swung against the urging force of the tension spring 547. Then, the swing arm 533b is swung clockwise in the valve body housing portion 511 inside the exterior body, and the valve body 520 is moved to the left via the engagement pin 542 engaged with the pin engagement groove 533h of the arm tip. When pressed, the valve body 520 slides to the left with a stroke corresponding to the swing angle of the operation unit 535. At this time, the front and rear end surfaces of the shutter portion 524 are guided by the front and rear transfer-inhibiting walls 505a and 505b of the lower ball tray 23 so that the valve body 520 supported by the slide rib 521r and the slide protrusion 526r on the lower surface of the valve body slides. The ball outlet 24 is opened by sliding to the left.

  The right edge of the swing arm 533b abuts the chamfered portion of the upper end corner of the shutter 524, and the angle at which the valve body 520 slides to the left and the operating member 530 swings clockwise is regulated. When the swing member 530 is swung to the position, the shutter portion 524 is disposed at the open position where the entire opening is opened on the back side of the ball outlet 24 (see FIGS. 47 and 49). The stored game balls flow down to the ball box BB prepared below through the ball outlet 24 and the discharge port 25.

  On the lower side of the ball outlet 24, a front transfer prevention wall 505 a is provided in front of the ball outlet 24, a rear transfer prevention wall 505 b is provided behind the ball outlet 24, and a right side transfer prevention wall 506 is provided on the right side of the ball outlet 24. A left-hand side transfer prevention wall 526 is disposed at the right end of the shutter portion 524. Therefore, when the valve body 520 is opened, the lower periphery of the ball outlet 24 is surrounded by these transfer-in prevention walls to form a duct-like discharge path, and the game flows down from the ball outlet 24 to the discharge port 25. A sphere does not enter between the base body 21 and the exterior body 22.

  When the ball removal operation is finished, the holding force that holds the operation unit 535 in the open position may be weakened. When the holding force is weakened, the tension spring 547 self-resets in the contracting direction due to the elastic force accumulated in the tension spring 547, the valve body 520 slides to the right in the valve body accommodating portion 511, and the shutter portion 524 is moved. The ball outlet 24 is closed. Accordingly, the swing arm portion 533b is swung counterclockwise by the engagement pin 542 that moves to the right, and the operation portion 535 is swung counterclockwise at a swing angle corresponding to the amount of movement of the valve body 520. The

  When the slide range restricting projection 528 at the right end of the shutter part comes into contact with the right-side transfer prevention wall 506, the movement of the valve body 520 to the right is restricted, and the shutter part 524 holds the ball outlet while maintaining a predetermined urging force. 24 is held at the closed position for closing the opening, and the operation portion 535 is disposed at the swing angle position before the ball removing operation. (See FIG. 48 and FIG. 50).

  As described above, in the ball removal mechanism BM5, the operation unit 535 for opening and closing the ball removal port 24 is provided on the left side of the lower ball tray 23 so as to be rotatable. Therefore, the firing handle 14 is held with the right hand. The ball removal operation can be easily performed with the left hand while rotating.

  In addition, although the operation unit 535 is provided on the front side of the lower ball tray structure 20, it is positioned on the left side of the lower ball tray 23 and is provided so as to be rotatable around a rotation axis extending in the front-rear direction. When the player stands up from the seat or sits down, or turns to the side to take a ball box left in the adjacent pachinko machine, the front surface that protrudes most forward in the lower ball tray structure 20 Even if it hits the center part, the probability of coming into contact with the operation unit 535 arranged on the left side is low, and the probability that the operation unit 535 is rotated by the contact is even lower, so that the game balls are scattered around. Can be greatly suppressed. In addition, the main component of the ball removal mechanism is configured by effectively using the lower region of the partition wall 64, and the operation unit 535 is disposed on the front side of the structure in front of the partition wall 64. It is possible to provide a ball removal mechanism having a good operability with the configuration. In addition, since the operation unit 535 is provided on the front surface side of the ball tray structure 20 and the operation unit 535 is disposed so as to cover the front of the bearing boss 512, it is possible to effectively prevent the invasion of tobacco ash, dust, and the like. It is a possible configuration.

  Therefore, according to the ball removal mechanism BM5 described above, it is possible to effectively prevent scattering of the game ball due to an erroneous operation, and to provide a ball removal mechanism with good operability for the player.

  In the above description, the cylindrical operation unit 535 having knurled eyes formed on the outer peripheral surface is illustrated as the operation unit for operating the operation member. However, FIG. 52 illustrates another configuration example of the operation unit in a rear view. In this way, a polygonal operation unit is used, and a screw (543, 545) for fixing the operation unit 535 and the swinging member 533 is used with a set screw 549 at the tip of the tip, and a salamometer hole is formed on the swinging shaft 531. And it can also comprise so that these members may be fixed.

  Further, like the operation portion 535 'shown in FIG. 52 (a), a projection 535t is provided on the outer peripheral surface of the knob portion 535a, and the cylindrical surface sandwiching the projection 535t can be cut back and forth to be elastically deformed in the radial direction. On the other hand, an engagement recess 512t is formed on the inner peripheral surface of the bearing boss 512 ′ to engage with the protrusion 535t when the valve body 520 is in the open position, and the operation portion 535 is in the open position of the valve body 520. The protrusion 535t and the engaging recess 512t are engaged with each other to lock the operating portion 535 at the swing angle position and hold the valve body 520 in the open position. This is also a preferable configuration. Further, as shown in FIG. 52 (b), an indicator portion 535s indicating the angular position of the operating portion is provided on the front side of the operating portion 535 ′, and the swinging angular position of the operating member 530 is indicated by the exterior body 22.

In the ball removal mechanism BM6, the main body 621 is horizontally displaced at a height position partially overlapping with the support base 67 in the receiving recess 60 as the valve body 620 is opened and closed. Therefore, in the ashtray structure of this configuration, a configuration example is shown in which the support pedestal 67 is partially cut out in accordance with this movement locus, and one spacer rib 67r is provided at the center of the lower surface of the support pedestal 67.

  The shutter portion 624 is formed in a plate shape that is offset upward in accordance with the height position on the lower surface side of the ball outlet 24 and protrudes to the right in parallel with the main body portion 621. Moreover, it is larger than the opening size of the discharge port 25 and is formed slightly smaller than the inner surface width of the front and rear transfer prevention walls 605a and 605b formed on the lower surface side of the lower ball tray 23.

  At the right end of the shutter portion 624, a leftward transfer prevention wall 626 is formed extending downward. The left side transfer prevention wall 626 closes the left side of the ball outlet 24 when the shutter 624 is opened, and the game ball flowing down from the ball outlet 24 does not enter between the base body 21 and the exterior body 22. In this way, it has the function of preventing the transfer-in and defining the closed position of the valve body 620 by engaging with the right-side transfer-in prevention wall 606 of the lower ball tray when the shutter part 624 is closed.

  A slit-like arm receiving groove 623 is formed in the front portion of the standing surface connecting between the main body portion 621 and the shutter portion 624 in accordance with the swing locus of the swing arm 633b, and the operation member 630 is formed. When the valve body 620 is positioned at the open position, the swing arm portion 633b is received in the groove so that the standing surface and the swing arm portion 633b do not interfere with each other. A center rib 624r is formed on the lower surface side of the shutter portion 624 so as to protrude downward and connect the standing surface and the left side transfer-in prevention wall 626 to suppress bending of the shutter portion 624 due to the load of the game ball. It is configured.

  The operation member 630 includes a swing shaft 631 that forms the central axis of the operation member, a swing member 633 having a swing arm portion 633b, an operation portion 635 that operates the operation member 630, and the like. The operation unit 635 is fixed to the unit, and the swinging member 633 is fixed to the lower part of the swinging shaft 631 by screws to form an integrated operation member 630.

  The rocking shaft 631 is a solid round rod shaft, the tip of which is formed so as to be detachable from the bearing hole 612b of the base body, and a stopper for fixing the operating portion 635 at a predetermined position in the upper and middle portions. Salamomi holes are machined to receive and lock the respective tip portions of the set screw 643 for fixing the screw 645 and the swinging member 633 (see FIGS. 64A and 64B). The swing shaft 631 is formed, for example, by cutting a steel rod having a predetermined wire diameter into a predetermined length, turning, drilling, or the like.

  The swing member 633 includes a hollow cylindrical collar portion 633a and a swing arm portion 633b provided at the lower end of the collar portion 633a. For example, the swing member 633 can be formed by injection molding using a resin material similar to that of the valve body 620. It is integrally formed by the forming means, or is formed integrally by caulking, welding, or the like between the metal collar portion and the arm portion. A bearing hole having an inner diameter slightly larger than the outer diameter of the swing shaft 631 is formed at the center of the collar portion 633a, and a set screw 643 is screwed and fastened at a predetermined position aligned with the swing shaft 631. A female thread portion for fixing the moving member 633 to the swing shaft 631 is formed in the direction perpendicular to the axis (see FIG. 64B).

  The length of the collar portion including the lower swing arm portion (the vertical dimension of the swing member 633) is determined when the upper end surface of the collar portion 633a of the swing member 633 is brought into contact with the lower surface of the support flange 612c. The lower surface of the swing arm portion 633b is set to be substantially the same height as the upper surface of the main body portion 621 of the valve body 620, and the swing member 633 fitted and supported by the swing shaft 631 is provided in the hub insertion hole. 612a and the bearing hole 612b are positioned in the front / rear / right / left direction (axial center position), and are fastened in the vertical direction and the angular direction by tightening a set screw 643 and locking it to the salamander hole.

  On the other hand, the swing arm portion 633b is formed in an arm shape projecting from the collar portion 633a in the direction orthogonal to the axis, and a boss engagement groove 633h for receiving and engaging the link boss 622 is formed at the tip portion thereof. It is formed in the direction in which the arm extends.

  The boss engaging groove 633h is formed so that its width dimension is substantially the same as the outer diameter of the link boss 622, while its length dimension swings when the operating portion 635 is swung clockwise and counterclockwise. The distal end portion of the arm portion 633b is formed larger than the displacement amount that is displaced in the front-rear direction. For this reason, when the boss engagement groove 633h is engaged with the link boss 622 of the valve body to swing the swing arm portion 633b, the boss engagement groove 633h and the link boss 622 are fitted in the left and right directions without play. The operating force is transmitted to the valve body 620, and the link boss 622 moves back and forth in the boss engagement groove 633h with respect to the longitudinal displacement of the arm tip accompanying the swing of the swing arm 633b. The relative displacement of the moving arm portion is allowed, and the valve body 620 is slid in the left-right direction with a stroke corresponding to the swing angle of the operation member 630.

  The operation portion 635 is an operation knob including a knob portion 635a in which a flat knob portion is erected on the upper surface of the circular knob, and a hub portion 635b that receives the swing shaft 631, for example, a commercially available knob knob or a multi-purpose knob. A square knob, a wing knob, etc. are used. A female screw portion for fixing the operating member 635 to the swing shaft 631 by screwing and fastening a set screw 645 to the hub portion 635b is formed in the direction perpendicular to the axis (see FIG. 64A).

  By attaching the valve body 620 and the operation member 630 configured as described above to the exterior body 22, and mounting the exterior body 22 assembled with each member so as to cover the front of the base body 21, the ball removal mechanism BM6. Is formed. For assembly, first, the hub portion 635b of the operation portion 635 is fitted to the upper end of the swing shaft 631, the set screw 645 is tightened, and the tip of the screw is engaged with the salami hole to fix the operation portion 635. Next, the swing member 633 is disposed between the support flange 612c and the bearing hole 612b, and the swing shaft 631 is inserted from above the hub insertion hole 612a to penetrate the swing member 633 and pivotally support the bearing hole 612b. Let Then, the support flange 612c is sandwiched between the hub portion 635b of the operation portion and the collar portion 633a of the swing member, and the set screw 643 is tightened from the side of the collar portion to engage the tip end of the tip with the salami hole of the swing shaft. Stop and fix the swinging member 630. As a result, the operating member 630 is assembled to the exterior body 22 without being pulled out even when the operating portion 635 is pulled upward, and is supported so as to be swingable around the swing shaft 631.

  Next, in a state where the swing arm 633b is swung to the right ball outlet 25 side, the valve body 620 is slid to the left from the ball outlet 25, and the link boss 622 is moved to the swing arm portion. Engage with the boss engaging groove 633h. Then, the operation unit 635 is rotated counterclockwise in plan view (hereinafter the same is omitted), the swing arm 633b is swung counterclockwise, and the valve body 620 is slid to the left. Let At this time, the arm intermediate portion is received in the arm receiving groove 623 that moves to the left along with the swing of the swing arm portion 633b, and the valve body 620 is slid to the left without any trouble. When the shutter portion 624 reaches the open position where the ball outlet 24 is opened, the left end surface of the main body portion 621 abuts on the right end surface of the support pedestal 67 to restrict the sliding movement to the left, and the valve body 620 is opened. Arranged in position.

  With the shutter 624 retracted to the left in this way, the exterior body 22 assembled with each member is mounted and screwed so as to cover the front of the base body 21. At this time, the partition wall engaging portion 601 of the base body engages with the partition wall 64 of the exterior body, and the right side transfer-in prevention wall 606 of the base body engages with the right side guide wall 616 of the exterior body, and the exterior body 22. Is positioned in the left-right direction and functions as a slide guide for guiding the exterior body 22. Below the partition wall 64, a valve body housing portion 611 is formed surrounded by the right wall surface of the housing recess 60, the left wall surface of the lower ball tray 23, the partition wall engaging portion 601, and the lower surface of the exterior body 22.

  Then, the operation portion 635 is rotated clockwise so that the shutter portion 624 is positioned at the closed position where the ball outlet 24 is closed, and one end of the tension spring 647 is attached to the valve-side latch hook 627 protruding to the lower surface side of the exterior body 22. The ball removal mechanism BM6 is assembled by engaging the other end of the tension spring 647 with the case-side locking hook 607 of the spring case 648 and screwing the spring case 648 to the case fixing boss 608 on the lower surface of the exterior body. Thus, the lower ball tray structure 20 having a ball removing mechanism is formed.

  When the ball removal mechanism BM6 is assembled in this way, the valve body 620 is accommodated and supported by the valve body accommodating portion 611 below the partition wall 64 so as to be horizontally displaceable in the left-right direction, and is always urged rightward by the tension spring 647. Thus, the left-side transfer prevention wall 626 at the right end of the shutter part is abutted against the right-side transfer prevention wall 606 and is restricted from moving, and the shutter part 624 is held at the closed position where the entire opening is closed on the back side of the ball outlet 24 ( (See FIGS. 60 and 62). Therefore, the game balls discharged to the lower ball tray 23 from the lower ball tray discharge passage through the discharge bucket 18 and the lower outlet 17 are regulated to flow down by the valve body 620 in the closed position and stored in the lower ball tray 23. .

  In order to perform the ball removal operation, the operation portion 635 is picked and rotated counterclockwise, and the operation member 630 is swung against the urging force of the tension spring 647. Then, the swing arm 633b is swung counterclockwise in the valve body housing portion 611 inside the exterior body, and the valve body 620 is moved to the left via the link boss 622 that engages with the boss engagement groove 633h at the arm tip. When pressed, the valve body 620 slides to the left with a stroke corresponding to the swing angle of the operation unit 635. At this time, the front and rear end surfaces of the shutter unit 624 are guided by the front and rear transfer-preventing walls 605a and 605b of the lower ball dish 23, and slide to the left so that the valve body 620 supported by the slide rib 621r on the lower surface of the main body unit slides. It moves and the ball outlet 24 is opened.

  The left end surface of the main body 621 abuts on the right end surface of the support pedestal 67, and the swing member is moved to an angular position where the slide movement of the valve body 620 to the left and the counterclockwise swing of the operation member 630 are restricted. When 630 is swung, the shutter unit 624 is disposed at an open position where the entire opening is opened on the back side of the ball outlet 24 (see FIGS. 59 and 49), and the game balls stored in the lower ball tray 23 Flows down to the ball box BB prepared below through the ball outlet 24 and the discharge port 25.

  On the lower side of the ball outlet 24, a front transfer prevention wall 605 a is provided in front of the ball outlet 24, a rear transfer prevention wall 605 b is provided behind the ball outlet 24, and a right side transfer prevention wall 606 is provided on the right side of the ball outlet 24. A left-hand side transfer prevention wall 626 is disposed at the right end of the shutter portion 624. Therefore, when the valve body 620 is opened, the lower periphery of the ball outlet 24 is surrounded by these transfer-in prevention walls to form a duct-like discharge path, and the game flows down from the ball outlet 24 to the discharge port 25. A sphere does not enter between the base body 21 and the exterior body 22.

  When the ball removal operation is finished, the holding force for holding the operation unit 635 in the open position may be weakened. When the holding force is weakened, the tension spring 647 self-resets in the contracting direction due to the elastic force accumulated in the tension spring 647, the valve body 620 slides rightward in the valve body housing portion 611, and the shutter portion 624 is moved. The ball outlet 24 is closed. As a result, the rocking arm 633b is swung clockwise by the link boss 646 that moves to the right, and the operation unit 635 is swung clockwise at a swinging angle corresponding to the amount of movement of the valve body 620.

  When the left-side transfer prevention wall 626 at the right end of the shutter part comes into contact with the right-side transfer prevention wall 606, the movement of the valve body 620 to the right is restricted, and the shutter part 624 holds out the ball while maintaining a predetermined urging force. The operation part 635 is disposed at a swing angle position before the ball removing operation, in a closed position where the entire opening is closed on the back side of the mouth 24. (See FIGS. 60 and 62).

  As described above, in the ball removal mechanism BM6, the operation unit 635 for opening and closing the ball removal opening 24 is located on the left side of the lower ball dish 23 and is provided on the upper surface side of the lower ball dish structure 20 so as to be rotatable. Therefore, the player can easily perform the ball removal operation with the left hand while rotating the firing handle 14 with the right hand and the distance between the lower ball tray structure 20 and the abdomen is in close contact. Even if it exists, the ball removal operation can be easily performed.

  In addition, since the operation unit 635 is provided on the upper surface side of the lower ball tray structure 20 so as to be able to rotate, a ball left when the player stands up or sits down from the seat or is left in an adjacent pachinko machine. Even if it hits the front of the lower ball tray structure 20 when trying to take a box, the operation unit will not be erroneously operated in the opening direction and the ball outlet will not be opened. There will be no situation that will scatter around. In addition, the main component of the ball removal mechanism is configured by effectively using the lower region of the partition wall 64, and the operation unit 635 is disposed in front of the partition wall 64 on the top surface of the ball tray structure. It is possible to provide a ball punching mechanism with good operability with a simple configuration. Moreover, since the operation part 635 is arrange | positioned covering the hub penetration hole 612a, it has the structure which can prevent effectively the penetration | invasion of tobacco ash, garbage, etc.

  Therefore, according to the ball removal mechanism BM6 described above, it is possible to effectively prevent the game balls from being scattered due to an erroneous operation, and to provide a ball removal mechanism with good operability for the player.

  In the above, the configuration example in which the operation unit 635 is disposed on the upper surface side of the lower ball dish structure 20 has been described. However, the operation unit 635 is disposed on the lower surface side of the lower ball dish structure 20, or It can also be arranged on both the upper and lower surfaces of the structure 20 to constitute a ball removal mechanism of this configuration form. For example, the operation member 630 is arranged upside down so that the operation unit 635 is disposed on the lower surface side of the exterior body 22, or in addition to the operation unit 635 on the upper surface side, the operation unit 630 is also disposed on the lower end portion of the swing shaft 631. It is also possible to configure a ball removal mechanism that can perform a ball removal operation at any of the upper and lower operation parts.
